& help
  This is the MUSH online help facility.
 
  Notes on help descriptions: 
        [text] - Text enclosed in []'s is optional.  The []'s are never typed
                 in as part of the command.
        <parameter> - Information parameter for a command.  The <>'s are
                      never typed in as part of the command.
 
  Syntax of help command:
    help [<command>]
 
  Some things to start with:
     help topics		(Main help topics)
     help command list		(List of commands) 	(@list commands)
     help flag list		(List of flags)		(@list flags)
     help function list		(List of functions)	(@list functions)
 
& COMMANDS
  Flag: COMMANDS ($)
 
  When set on an object, when a command match is done, it checks the 
  object for attributes of the form '$<pattern>:<commandlist>'. If the 
  command matches the pattern, then <commandlist> is executed.
 
  In other words, it checks the object for arbitrary user-defined 
  $commands.
 
  Depending on your MUSH configuration, this flag might or might not
  be necessary for Arbitrary Commands to be checked.
 
  See 'help Arbitrary Commands' for more details.

& drop 
  Command: drop[/<switch>] <object>
           drop[/<switch>] <exit>
 
  The first form removes <object> from your inventory and puts it in your
  location, except for the following special cases: Dropping a STICKY thing
  sends it home, and dropping a thing in a room with a drop-to sends the thing
  to the drop-to location.
 
  The second form removes <exit> from your list of exits and adds it to the
  list of exits for the current location.  Anyone in the same location as
  you may then use the exit to travel to the exit's destination.  You can
  only drop exits when you own the location where you are dropping them.
 
  The following switch is recognized:
     /quiet   - Don't perform the @odrop/@adrop attributes on the dropped
                 object.  This switch only works if you control the object.
 
  'throw' is the same as 'drop'.
  See also: get, @adrop, @drop, @odrop, DROP-TO, STICKY.  

& enter
  Command: enter[/<switch>] <object>
  The enter command is used to enter an object. Insides of objects are best
  used for vehicles, or storage spaces when you don't have a home (or even
  as a floating home).  In order to enter an object you must either own it or
  it must have its ENTER_OK flag set, and you must also pass the object's
  EnterLock (if it has one).
 
  The following switch is recognized:
     /quiet   - Don't perform the @oenter/@aenter or @oefail/@aefail
                attributes on the entered object, and don't perform the
                @oxleave attribute on your current location.  This switch
                only works if you control the object being entered.
 
  See also: leave, @aefail, @aenter, @efail, @enter, @idesc, @lock, @oefail,
            @oenter, @oxleave, ENTER_OK.

& examine
  Command: examine[/<switches>] <object>[/<wild-attrib>]
  Displays all available information about <object>.  <object> may be an
  object, 'me' or 'here'. You must control the object to examine it, or it
  must be set VISUAL.  If you do not own the object, you will just see the
  name of the object's owner, and optionally any public attributes and 
  attributes owned by you set on the object.
 
  If an attribute is owned by a player other than the owner of the object,
  the number of the attribute owner is shown in parentheses immediately
  following the attribute name.  Flag letters may appear in parentheses also,
  to indicate the status of the attribute; see 'help @set2' for details.
 
{ 'help examine2' for more }
& examine2
  If you specify a wildcarded attribute name, then only those attributes
  that match are shown.  So, 'exam me/v?' will show all your attributes that
  start with v and are two characters long.
 
  The following switches are available:
     /brief  - When examining an object you don't control, show only the
               owner's name. 
     /full   - When examining an object you don't control, show any public
               attributes set on the object in addition to the owner's name.
     /parent - Includes attributes that are not present on the object itself
               but which are inherited from the object's parent.
  See also: look, @decompile, VISUAL, ATTRIBUTE OWNERSHIP.

& get
  Command: get[/<switch>] <object>
           get[/<switch>] <exit>
           get[/<switch>] <object>'s <sub-object>

  The first form picks up <object> from your location and adds it to your
  inventory.  It will fail if the object is locked against you, or if you
  are inside a player or object that you don't control and which isn't
  set ENTER_OK.
 
  The second form takes an exit from your location and adds it to you.
  Anyone inside you may then use the exit to travel to the exit's destination.
  You may take exits that you own, and exits owned by others in locations that
  you own.
 
  The third form takes <sub-object> from <object> and adds it to your
  inventory.  <object> must be ENTER_OK and <sub-object> must not be locked
  against you for this to work.  The lock on <object> is not checked.
{ 'help get2' for more }
& get2
  The following switch is recognized:
     /quiet   - Don't perform the @osucc/@asucc or @ofail/@afail attributes
                on the target object.  This switch only works if you control
                the object.
 
  <object> and <sub-object> may be either players or things.
  'take' is the same as 'get'.
  See also: drop, @afail, @asucc, @fail, @ofail, @osucc, @succ, ENTER_OK,
            FAILURE, SUCCESS.
& give
  Command: give <player>=<amount/object>
  Gives player the specified amount of money or <object>. You can't give
  someone money if their new total would be greater than 10000 (No reason to
  get greedy).  You may also give players objects, but the other player must
  be set ENTER_OK to receive something you give. 
  See also: @apay, @cost, @opay, @pay, ENTER_OK.

& goto
  Command: goto[/<switch>] <direction>
           goto[/<switch>] home
           <direction>
           home
 
  Moves you in the specified direction, assuming that the direction is not
  locked against you.  'move home' is a special command that returns you to
  your home. The word 'move' may be omitted.
 
  The following switch is recognized:
     /quiet   - Don't perform the @osucc/@asucc/@odrop/@adrop or @ofail/@afail
                attributes on the exit being used.  This switch only works if
                you control the exit.
 
  'move' is the same as 'goto'.
  See also: enter, home, leave, 

& inventory
  Command: inventory
  Lists what you are carrying and how much money you have.

& kill
  Command: kill <player> [=<cost>]
  Attempts to kill the specified player. Killing costs <cost> coins, which
  gives you a <cost>% chance of killing the player. Thus, spending 100 
  coins always works (except against wizards and immortals, who can never be
  killed). Players cannot be killed in rooms which have been set HAVEN or
  which they control.  If you don't specify a cost, the default is 10 (for a
  10% chance of success).  The player, if killed, receives <cost>/2 coins in
  insurance.
  See also: @akill, @kill, @okill, BEING KILLED, IMMORTAL, WIZARD.

& leave
  Command: leave[/<switch>]
  This command leave allows you to exit an object you have entered, arriving
  in the same location as the object. You may not leave an object if you fail
  that object's LeaveLock (but you may still @teleport out, use an exit inside
  the object, or go home).
 
  The following switch is recognized:
     /quiet   - Don't perform the @oleave/@aleave or @olfail/@alfail
                attributes on the entered object, and don't perform the
                @oxenter attribute on your new location.  This switch
                only works if you control your current location.
 
  See also: enter, @lock, ENTER_OK, @aleave, @alfail, @leave, @lfail, @oleave,
            @olfail, @oxenter.
& LOGOUT
  Command: LOGOUT
  Disconnects you from your character without breaking the network connection
  to the game.  You may then log in to another character.  The LOGOUT command
  must be entered in all capitals.
  See also: QUIT.

& look
  Command: look[/<switches>] [<object>]
  Displays the description of <object>, or the room you're in if you don't
  specify an object.  Specifying object as <name> or #<dbref> or 'me' or
  'here' is legal.  You can also use look to look at objects held by other
  people, just use 'look <person>'s <object>'.
 
  You may use the /outside switch to look at the location of your current
  location (useful if you are inside a vehicle or other object).  You may
  also look at other objects in the 'outer' location, but you may not
  use the possessive form with the /outside switch (ie: "look/outside
  <person>'s <object>" won't work).
  
  'read' is the same as 'look'.
 
  See also: @adesc, @describe, @odesc.

& move
  Command: move[/<switch>] <direction>
           move[/<switch>] home
           <direction>
           home
 
  Moves you in the specified direction, assuming that the direction is not
  locked against you.  'move home' is a special command that returns you to
  your home. The word 'move' may be omitted.
 
  The following switch is recognized:
     /quiet   - Don't perform the @osucc/@asucc/@odrop/@adrop or @ofail/@afail
                attributes on the exit being used.  This switch only works if
                you control the exit.
 
  'goto' is the same as 'move'.
  See also: enter, home, leave.
& news
  Command: news [<topic>]
  Shows you the current news for the MUSH. It is highly recommended that
  you check the news daily for new information.  Otherwise, the wizards will
  have no pity on you for messing up with the new commands.

& OUTPUTPREFIX
  Command: OUTPUTPREFIX <string>
  Causes <string> to be output on a line by itself before printing the
  results of each command.  This command is intended for use by external
  robot programs, and may be restricted to players whose ROBOT flag is set.
  The OUTPUTPREFIX command must be entered in all capitals.
  See also; @robot, OUTPUTSUFFIX, ROBOT.

& OUTPUTSUFFIX
  Command: OUTPUTSUFFIX <string>
  Causes <string> to be output on a line by itself after printing the results
  of each command.  This command is intended for use by external robot
  programs, and may be restricted to players whose ROBOT flag is set.
  The OUTPUTSUFFIX command must be entered in all capitals.
  See also; @robot, OUTPUTPREFIX, ROBOT.

& page 
  Command: page <player> [=[<control>]<message>]
 
  This command sends <message> to <player>.  If you do not specify a message,
  it tells a player that you are looking for them, and tell the player where
  you are.  You may use either the player's name or alias, and you may also
  give a string that uniquely matches the start of a player's name on the WHO
  list.
 
  You can format the message one of several ways by specifying ':', ';', or
  '"' as the first character of the message.  ':' and ';' format the message
  as 'From afar, <player> <message>', with ';' omitting the space between
  <player> and <message>.  '"' formats the message in normal page format
  (this is the default).
 
  If your Idle attribute is set to something, then it is sent to anyone
  who successfully pages you.  This is useful for when you are away from
  your terminal for a short while.
{ 'help page2' for more }
& page2  
  You can selectively disable pages from certain players with the '@lock/page'
  command (players must pass the lock in order to page you).  If someone
  cannot page you, they will be sent a message including of your Reject
  attribute if they try.  If someone pages you while you are not connected,
  they are sent a message including your Away attribute.
 
  See also: pose, say, whisper, :, ;, ", @pemit, @away, @idle, @reject.

& pose
  Command: pose[/<switches>] <message>
  Displays <message> to everyone in your current room, preceded by your name
  and optionally a space.  Example: the command 'pose jumps for joy' produces
  '<yourname> jumps for joy'.
 
  The following switches are available:
     /default - (default) Put a space between your name and the message
                (ie, display '<name> <message>').
     /nospace - Don't put a space between your name and the message
                (ie, display '<name><message>').
 
  See also: page, say, whisper, :, ;, ".

& PUEBLOCLIENT
  Command: PUEBLOCLIENT
 
  This command notifies the MUSH that one is using a client that supports
  the Pueblo extensions. Such a client normally sends this string
  automatically; users probably will never need to type this.
 
& QUIT    
  Command: QUIT
  Logs you out and disconnects you from the game. Must be in all capitals.  
  See also: LOGOUT.

& read 
  Command: read [<object>]
  Displays the description of <object>, or the room you're in if you don't
  specify an object.  Specifying object as <name> or #<dbref> or 'me' or
  'here' is legal.  You can also use look to look at objects held by other
  people, just use 'read <person>'s <object>'.
 
  You may use the /outside switch to look at the location of your current
  location (useful if you are inside a vehicle or other object).  You may
  also look at other objects in the 'outer' location, but you may not
  use the possessive form with the /outside switch (ie: "read/outside
  <person>'s <object>" won't work).
  
  'look' is the same as 'read'.

& ;
  Command: ;<message>
  This command is much like the ':' command, except that no space is inserted
  between your name and the action.  Example: the command ';'s watch beeps.'
  produces '<yourname>'s watch beeps.'.
 
  Warning: This command does not work in command lists run from an attribute
  because the ';' is treated as the command separator.  Use pose/nospace
  instead.
 
  See also: page, pose, say, whisper, :, ".

& :
  Command: :<message>
  Displays <message> to everyone in your current room, preceded by your name
  and a space.  Example: the command ':jumps for joy' produces
  '<yourname> jumps for joy'.
  See also: page, pose, say, whisper, ;, ".

& "
  Command: "<message>
  Says <message> out loud to everyone in your current room.  Example:
  the command '"Where is the movie theater?' produces
  '<yourname> says "Where is the movie theater>"'.  Note that the closing
  double quote is automatically added.
  See also: page, pose, say, :, ".

& #
  Command: #<number> <command>
  Forces the object whose database number is <number> to perform <command>.
  Example: '#1033 move north' forces object #1033 to go north (assuming that
  you control it).  The same restrictions that apply to @force also apply to
  this command.
  See also: @force.

& \\
  Command: \\<message>
  Outputs <message> to everyone in your current room without embellishment.
  Example: the command '\\A chill falls over the room.' produces
  'A chill falls over the room.'
  See also: @emit, @oemit, NOSPOOF.

& say
  Command: say <message>
  Says <message> out loud to everyone in your current room. You can also
  use '"<message>'.
  See also: page, pose, whisper, :, ;, ".

& score
  Command: score
  Displays how much money you have.  Helpful to see if any machines are
  looping.
  See also: @ps, LOOPING.

& SESSION
  Command: SESSION
  Displays information on how many characters you have sent and received
  during this session, and which (Internal) port you are connected to on the
  mush.  It must be typed in all uppercase.
 
  Example:
    > SESSION
                                     Characters Input----  Characters Output---
    Player Name     On For Idle Port Pend  Lost     Total  Pend  Lost     Total
    Mortal           00:06   0s   16    0     0        44   156     0      2679
    2 Players logged in.
 
  Pending characters are those waiting to be acted on as commands (for input)
  or waiting to be sent out over the network (output).  Lost characters are
  due to overflowing either the MUSH's input or output buffers, either as the
  result of running a single command that produces too much output (such as
  @find and @search commands that match a large number of objects), or from
  typing too much on one line.
 
  Note: your Pending count for output will always be nonzero, as the output
  of the SESSION command hasn't been sent out over the network yet.

& take
  Command: take[/<switch>] <object>
           take[/<switch>] <exit>
           take[/<switch>] <object>'s <sub-object>
 
  The first form picks up <object> from your location and adds it to your
  inventory.  It will fail if the object is locked against you, or if you
  are inside a player or object that you don't control and which isn't
  set ENTER_OK.
 
  The second form takes an exit from your location and adds it to you.
  Anyone inside you may then use the exit to travel to the exit's destination.
  You may take exits that you own, and exits owned by others in locations that
  you own.
 
  The third form takes <sub-object> from <object> and adds it to your
  inventory.  <object> must be ENTER_OK and <sub-object> must not be locked
  against you for this to work.  The lock on <object> is not checked.
{ 'help take2' for more }
& take2
  The following switch is recognized:
     /quiet   - Don't perform the @osucc/@asucc or @ofail/@afail attributes
                on the target object.  This switch only works if you control
                the object.
 
  <object> and <sub-object> may be either players or things.
  'get' is the same as 'take'.
  See also: drop, @afail, @asucc, @fail, @ofail, @osucc, @succ, ENTER_OK,
            FAILURE, SUCCESS.

& throw
  Command: throw[/<switch>] <object>
           throw[/<switch>] <exit>
 
  The first form removes <object> from your inventory and puts it in your
  location, except for the following special cases: Dropping a STICKY thing
  sends it home, and dropping a thing in a room with a drop-to sends the
  thing to the drop-to location.
 
  The second form removes <exit> from your list of exits and adds it to the
  list of exits for the current location.  Anyone in the same location as
  you may then use the exit to travel to the exit's destination.  You can
  only drop exits when you own the location where you are dropping them.
 
  The following switch is recognized:
     /quiet   - Don't perform the @odrop/@adrop attributes on the dropped
                 object.  This switch only works if you control the object.
 
  'drop' is the same as 'throw'.
  See also: get, @adrop, @drop, @odrop, DROP-TO, STICKY.  

& use
  Command: use <object>
  Uses <object>.  Some objects will do interesting, useful, or dangerous
  things when used, for instance, using a camera should result in a 
  picture being taken.
  See also: @ause, @ouse, @use.

& version
  Command: version
  Displays the version of MUSH that is running and the date it was last
  rebuilt.

& whisper 
  Command: whisper <player>=<message>
  Whispers the message to the named person, if they are in the same room as
  you. No one else can see the message that you whisper.
 
  You can format the message one of several ways by specifying ':', ';', or
  '"' as the first character of the message.  ':' and ';' format the message
  as 'You sense <player> <message>', with ';' omitting the space between
  <player> and <message>.  '"' formats the message in normal whisper format
  (this is the default).
  See also: page, pose, say, :, ;, ".

& WHO
  Command: WHO <prefix>
  Displays a list of players currently connected to the MUSH.
  The WHO report tells you how long a player has been on, how long they
  have been inactive, and what they are doing (if they have used the @doing
  command).  If <prefix> is specified, only players whose names start with
  <prefix> are listed.  The WHO command must be entered in all capitals.
  See also: @doing.

& &
  Command: &<attribute> <object>[=<value>]
  Synonym: @set <object> = <attribute>:[<value>]
 
  Sets the attribute named <attribute> on <object> to <value>.  If
  <attribute> is not a predefined attribute (like ofail or va), then it is
  created.  Attributes so created are called user-named attributes.
  Attribute names may only contain letters, numbers, and the characters
  < -_.@#$^&*~?=+| >, and must start with a letter.  The names of user-named
  attributes may not be abbreviated (an attempt to get the value of the
  attribute will fail, and an attempt to set will create a new attribute).
  The & command may be used to set predefined attributes (in this instance,
  '&<attr> <object>=<value>' is equivalent to '@<attr> <object>=<value>').
 
  See also: @set.

& @@
  Command: @@ <args>
 
  This command does nothing, therefore it is useful for putting comments into
  a MUSH program.  Be careful that ()'s and {}'s in the (otherwise ignored)
  arguments are nested correctly, lest your command-ending ; be trapped
  inside.
 
  Example:
     @va me=$foobar *:@fo #1234=%0;@@ This controls my foobar puppet.

& @chown
  Command: @chown <object>[=<player>]
           @chown <object>/<attr>[=<player>]
  The first form changes the ownership of <object> to <player> (default is
  to yourself).  Objects may be things, rooms or exits. To chown things, you
  have to be carrying the thing. For rooms or exits, you have to be in the
  room. Objects must have the CHOWN_OK flag set before they may be @chowned.
  In a room, the command used must be @chown here = <name>, and for an object,
  you must be very specific.
 
  The second form changes the ownership of the indicated attribute on <object>
  to <player> (default is the owner of the object).  You may only @chown
  unlocked attributes.  You may @chown unlocked attributes on objects that
  you own to yourself, and you may also @chown attributes that you own on
  objects owned by others to the owner of the object.
 
  When an object is @chowned, all unlocked attributes on the object are
  automatically @chowned as well, locked attributes remain owned by their
  original owners.
 
  The HALTED flag is automatically set on the new copy of the object.
  Players can't be @chowned; they always own themselves. 
  See also: @lock, @Unlock, CHOWN_OK, ATTRIBUTE OWNERSHIP.

& @clone
  Command: @clone[/<switches>] <object>[=<newname/cost>]
 
  Creates an exact duplicate of <object> that is owned by you and (for things
  and exits) puts it in your current location.  You may have the object put
  in your inventory (or your exitlist in the case of cloning exits) by using
  the /inventory switch.
 
  You may clone your own objects, plus VISUAL objects owned by others.
  The INHERIT and WIZARD bits of the (new) object are cleared when the object
  is cloned.  If <newname> is specified, it is used as the name instead of
  the original name.
 
  If you clone a linked exit, an attempt is made to link the clone to the
  same location.  Except when using the /inventory switch, you can only clone
  exits when you own your current location.
 
  If you clone a room with a drop-to, an attempt is made to link the drop-to
  to the same location.
 
  If the original object was owned by you, then the ACLONE attribute is run
  in the new attribute, otherwise the new object is set HALTED.  Exits and
  contents of cloned objects are not cloned.
{ 'help @clone2' for more }
& @clone2
  The following switches are available:
     /cost       - Treat the argument after the = as the cost of the new
                   object, not the name.
     /inherit    - Don't reset the INHERIT bit on the new object.
     /inventory  - Create the new object in your inventory (or your exitlist,
                   in the case of cloning exits).
     /location   - Create the new object in your location (default).
     /parent     - Set the new object's parent to be the template object and
                   don't copy the attributes.
  See also: @create, @decompile, @destroy, VISUAL.

& @create
  Command: @create <name> [=<cost>]
  Creates a thing with the specified name.  Creation costs either <cost>
  or 10 coins, whichever is greater. The value of a thing is proportional
  to its cost, specifically, value=(cost/5)-1.  The value may not be greater
  than 100, values that would be greater than 100 are rounded down to 100.
  See also: @destroy, TYPES OF OBJECTS.

& @destroy
  Command: @destroy[/<switches>] <object>
  This command destroys <object> and refunds its cost of creation to its
  owner.  You must own <object> in order to @destroy it, unless its
  DESTROY_OK flag is set, in which case anyone holding it may @destroy it.
  Rooms, exits, and objects may be destroyed, although the the actual
  destruction of rooms is delayed for up to ten minutes and the GOING flag
  is set on the victim room.  Clearing the GOING flag on the room spares it
  from destruction.
 
  The @destroy command will not destroy objects with the SAFE flag set unless
  the /override switch is specified.  The DESTROY_OK flag overrides the
  protection given by the SAFE flag.
 
  The following switches are available:
    /override  - Negate protection offered by the SAFE flag.
  See also: DESTROY_OK, SAFE.

& @dig
  Command: @dig[/<switches>] <name> [= <exitlist> [, <exitlist>] ]
  Creates a new room with the specified name and displays its number. This 
  command costs 10 coins. If the [= <exitlist>] option is used, an exit will
  be opened from the current room to the new room automatically.  If the
  second <exitlist> option (after the comma) is specified, an exit from the
  new room back to the current room with the specified [Exits] name is
  opened.  Either exit creation may fail if you do not have sufficient
  rights to the current room to open or link the new exit.
  Example: The command
 
     @dig Kitchen = Kitchen;k;north;n,south;s
 
  will dig a room called Kitchen, and open an exit called 'Kitchen' in your
  current room.  The ; symbol means that you may enter the exit by typing
  'k', 'north' or 'n' also.  This command also opens the exit 'south;s' from
  'Kitchen' back to where you are.  Only the first Exit name is displayed in
  the Obvious exits list.
 
  If you specify the /teleport switch, then you are @teleported to the
  room after it is created and any exits are opened.
 
  See also: @destroy, @link, @open, LINKING, TYPES OF OBJECTS.

& @doing
  Command: @doing[/<switches>] [<message>]
 
  Sets your doing message, which appears after your name in the WHO report.
 
  The following switches are available:
     /message - Sets your Doing string in the WHO report. (default)
     /poll    - Displays the current Doing poll from the WHO report.
 
  See also: WHO.

& @dolist
  Command: @dolist[/<switch>] [<delimiter>] <list>=<action>
  <list> is a list of strings, which can be object numbers, attributes, or
  arbitrary words.  <action> is a command to perform once for each item in
  <list>, replacing the special symbol ## with the corresponding item from
  <list>. By default, @dolist considers each item in <list> to be separated
  with spaces. If you specify the /delimit switch, then each item is
  considered to be separated by <delimiter>. <delimiter> must be a single
  character.
 
  If present, <switch> can be any of:
    /space   - (Default) List elements are separated by spaces.
    /delimit - List elements are separated by <delimiter>.
    /notify  - Queues a "@notify me" after all the @dolist'd commands.
 
  This command is particularly handy with lcon() and lexits(). A few examples:
 
    @dolist [lcon(here)] = "[name(##)](##)
    @dolist [lcon(here)] = @switch [get(##/last)]=*1990*,"[name(##)]
    @va me = va vb vc
    @dolist [get(me/va)] = @emit [get(me/##)]
    @dolist Frodo Bilbo Gandalf = page ## = HELP!!!!  I've fallen into a pit.
    @dolist/delimit , {Frodo, Bilbo Baggins, Gandalf} = page ## = HELP!!!!
  See also: iter(), parse().

& @drain
  Command: @drain <object>
  Discards all commands waiting on the semaphore <object> and resets the
  semaphore to its initial state.
  See also: @notify, @ps, SEMAPHORES

& @edit
  Command: @edit <object>/<wild-attr> = <search>,<replace>
           @edit <object>/<wild-attr> = ^,<text>
           @edit <object>/<wild-attr> = $,<text>
  This command edits the contents of one or more attributes of an object,
  eliminating the need to retype a long attribute in order to make a simple
  change.  In the first form, all occurrences of <search> in the specified
  attribute of the named object are replaced with <replace>.  Use curly
  braces ({ and }) around <search> or <replace> if they contain commas.
  The second and third form prepend and append <text> to the selected
  attributes, respectively.
 
  If <wild-attr> contains wildcard characters, then all attributes that
  match are edited.

& @emit
  Command: @emit[/<switches>] <message>
  Sends <message> to everyone in your current location without prefixing it by
  your character name.  You can also send the message to everyone in the room
  that contains the object you are inside with the /room switch.
 
  The following switches are available:
     /here  - Sends the message to everyone in the same location as you.
     /room  - Sends the message to everyone in the room that contains the
             object you are in.  Starting from your location, this switch
             'leaves' objects until it reaches a room, and @emits the message
             there.
  If both switches are specified, the message is sent to both places.  If
  neither is specified, /here is assumed.

  There is an also an '/html/' switch, which sends the output in HTML
  format. (Pueblo support only.)
 
  Some MUSHes may restrict the use of this command.
  See also: @femit, @oemit, @pemit, SPOOFING.

& @entrances
  Command: @entrances [[<object>][,<low>[,<high>]]]
 
  Lists links from elsewhere to the specified object (default: your current
  room).  For rooms, exits and drop-to's, leading to the room and players
  and objects whose home is in the room are listed.  For players and objects,
  lists exits leading to them.  Because this command is computationally
  expensive, it costs 100 coins.  <low> and <high> can be used to indicate
  where to start and stop the search, respectively.
 
  Examples:
    > @entrances             <- all links to here
    > @entrances object      <- all links to object
    > @entrances ,100,200    <- all links to here from #100 to #200
    > @entrances me,1000     <- all links to me from #1000 and above.
  See also: @link, @unlink.

& @femit
  Command: @femit[/<switches>] <object>=<message>
  Forces <object> to emit <message>.  This command is similar to the command
  '@force <object> = @emit <message>', except that it will work so long as
  you own the object, whereas @force may fail if the object has its INHERIT
  flag set and the object performing the @force does not.
 
  The following switches are available:
     /here  - Sends the message to everyone in the same location as <object>.
     /room  - Sends the message to everyone in the room that contains the
              object that <object> is in.  Starting from your location, this
              switch 'leaves' objects until it reaches a room, and @emits the
              message there.

  If both switches are specified, the message is sent to both places.  If
  neither is specified, /here is assumed.
 
  Some MUSHes may restrict the use of this command.
  See also: @emit, @fpose, @fsay, INHERIT, SPOOFING.

& @find
  Command: @find <name>[,<low>[,<high>]]
 
  Displays the name and number of every room, thing, or player that you
  control whose name matches <name>. Because the command is computationally
  expensive, it costs 100 coins.
 
  <low> and <high> may be used to restrict the range of objects that are
  searched, if they are given then the search starts at object #<low> and ends
  at object #<high>.
 
  Examples:
    > @find Lost Room
    > @find Secret Device,12000,14000
  See also: @search.

& @force
  Command: @force <player/object>=<command>
  Forces the game to act as though <player/object> had entered <command>.
  You may only force objects that you control.  Objects may not force players
  unless either the object or the player has their INHERIT flag set, and
  objects that do not have their INHERIT flag set may not force objects that
  do.  If the victim is specified by number, you may use an alternate form
  of the command, '#<number> <command>'.
  See also: puppets.

& @fpose
  Command: @fpose[/<switches>] <object>=<message>
  Forces <object> to pose <message>.  This command is similar to the command
  '@force <object> = :<message>', except that it will work so long as you
  own the object, whereas @force may fail if the object has its INHERIT flag
  set and the object performing the @force does not.
 
  The following switches are available:
     /default - (default) Put a space between the name of the object and
                the message (ie, send '<name> <message>').
     /nospace - Don't put a space between the name of the object and the
                message (ie, send '<name><message>').
  See also: @femit, @fsay, pose, :, ;, INHERIT.

& @halt
  Command: @halt [<object>]
  Halts all commands being run by <object>, or by the object running the
  command if no <object> is given.  If the object to be halted is a player,
  then all commands being run by objects owned by that player are halted.
  Use this command to stop runaway objects and infinite loops.
  The process of halting an object involves removing all commands waiting
  to be run by the object from the queue and refunding the queue deposit.
  Halting an object does not affect commands waiting on it as a semaphore.
  See also: @drain, @notify, kill, HALTED, SEMAPHORES.

& @last
  Command: @last <player>
  This command displays a short 'connection history' for <player>, showing
  recent successful and failed connection attempts, as well as the total
  number of successful and failed connections.
  You can only display information about yourself.

& @link
  Command: @link <object>=#<number>/here/home
 
  When used on a player or a thing, this command sets the object's home
  to the indicated location.  The destination must be owned by you or be an
  ABODE room.
 
  When used on a room, this command sets the room's drop-to, where objects
  dropped in the room go.  The destination must be a room that is either owned
  by you or is LINK_OK.
 
  For exits, this command sets the destination if the exit is currently
  unlinked, and you control the destination or it is set LINK_OK. You can
  @link an unlinked exit regardless of who owns it or the lock set on it;
  you are made the owner if you successfully link to the destination. 
  Linking an exit costs 1 coin, and if the exit was owned by someone else,
  you also reimburse the the former owner 1 coin (making the total cost to
  you 2 coins).
 
{ 'help @link2' for more }
& @link2
  If you are not a Wizard, in order to link to a destination, you must
  pass its LinkLock (even if you are the owner of that destination).
 
  Note that in all the above cases that it is the player performing the @link
  command that must pass the LinkLock, not the object being linked.
  Therefore, you should use the '$' lock qualifier if you want to prevent
  specific players from linking to your LINK_OK locations, as simply locking
  against '*<playername>' does not lock out their puppets.
 
  See also: @dig, @open, @unlink, DROP-TOS, HOMES, LINKING.

& @list
  Command: @list [<option>]
  Lists information from internal databases.  Information is available
  about the following options:
    attributes      - Valid object attributes.
    commands        - Commands that you may use (excluding the 
                      attribute-setting commands as well as any exits, and
                      $-commands available).
    costs           - Lists the costs associated with many commands and
                      actions.
    default_flags   - Lists the flags that new objects receive by default
                      when created.
    flags           - Lists the name and letter of all the flags.
    functions       - Lists all the available functions.
    options         - Lists several global options and limits.
    switches        - Lists what commands support switches and the switches
                      that they do support.
  The information provided by the @list command is definitive, as it reads
  the internal tables to produce the information it displays.  Specifying
  @list with no argument lists the options you may use.

& @listmotd
  Command: @listmotd
  Displays the current message-of-the-day.  Note that it is displayed when
  you connect to your character.

& @lock
  Command: @lock[/<whichlock>] <object>=<key>
           @lock <object>/<attrib>
 
  The first form locks <object> to a specific key(s).  Type 'help @lock keys'
  for a list of the keys you may use.
 
  <whichlock> indicates which lock you want to set on the object.  If you
  don't specify one, you set the Default lock. Type 'help @lock locks' for
  a list of the locks you may set and what they are used for.
 
  The second form locks the indicated attribute of the named object, so that
  when the object is @chowned, the attribute will remain owned by you.
  It may also be used when you own an attribute on an object that you do not
  own, in this case it prevents the object's owner from @chowning the
  attribute to himself, and prevents anyone from modifying or removing the
  attribute.
 
  See also: @chown, @unlock.

& @lock locks
  You can set the following locks:
 
     DefaultLock:  Exits:          controls who may traverse the exit to
                                   its destination.
                   Rooms:          controls whether the player sees the SUCC
                                   or FAIL message for the room following the
                                   room description when looking at the room.
                   Players/Things: controls who may GET the object.
     EnterLock:    Players/Things: controls who may ENTER the object if the
                                   object is ENTER_OK.
     GiveLock:     Players/Things: controls who may give the object.
     LeaveLock:    Players/Things: controls who may LEAVE the object.
     LinkLock:     All but Exits:  controls who may link to the location if the
                                   location is LINK_OK (for linking exits or
                                   setting drop-tos) or ABODE (for setting
                                   homes)
     PageLock:     Players:        controls who may page the player.
     ParentLock:   All:            controls who may make @parent links to the
                                   object.
     ReceiveLock:  Players/Things: controls who may give things to the object.
{ 'help @lock locks2' for more }
& @lock locks2
     TeloutLock:   All but Exits:  controls who may teleport out of the
                                   location.
     TportLock:    Rooms/Things:   controls who may teleport there if the
                                   location is JUMP_OK.
     UseLock:      All but Exits:  controls who may USE the object, GIVE the
                                   object money and have the PAY attributes
                                   run, have their messages heard and possibly
                                   acted on by LISTEN and AxHEAR, and invoke
                                   $-commands stored on the object.
     UserLock:     All:            Not used by MUSH, is intended to be used
                                   in MUSH programming where a user-defined
                                   lock is needed.

& @Lock keys
 
  You may use the following keys when setting locks.  For information about
  a particular type of key, type 'help @lock <keytype>'.
 
  Key Type    Form in @Lock Command
  ----------  ------------------------------
  Normal      <object>
  Is          =<object>
  Carry       +<object>
  Ownership   $<object>
  Indirect    @<object>
  Attribute   <attribute>:<wildcard-pattern>
              +<attribute>:<wildcard-pattern>
              =<attribute>:<wildcard-pattern>
  Evaluation  <attribute>/<value>
  Compound    <key> & <key>
              <key> | <key>
              !<key>
              ( <key> )

& @lock attribute
  ATTRIBUTE LOCKS:
 
  Key: <attribute>:<pattern>
       +<attribute>:<wildcard-pattern>
       =<attribute>:<wildcard-pattern>
 
  You may lock on whether a specific attribute on the player attempting to
  pass the lock matches a pattern.  Example: '@lock thing=sex:m*' will lock
  thing to anyone whose sex starts with an M. Wild cards, greater than and
  less than may be used, for example: '@lock a-f=name:<g' will lock the exit
  a-f against any one whose name is higher than f.
 
  Both the player testing the lock and every object in his inventory is
  checked, the player passes the lock if any of those objects passes the lock.
  If the attribute name is prefixed by a = then only the player is checked.
  Similarly, if the attribute name is prefixed by a + then only objects in
  the player's inventory are tested.
 
{ 'help @lock attribute2' for more }
& @lock attribute2
  Note: you may lock against any attribute, but the locked object must be
  able to read the attribute from the player attempting to pass the lock or
  the lock will fail.
 
  Examples:
    > @lock men's room=sex:m*
    > @lock a-f=name:<g
    > @lock post office=email:*@*
  See also: ATTRIBUTE OWNERSHIP, @lock evaluation.

& @lock evaluation
  EVALUATION LOCKS:
 
  Key: <attribute>/<value>
 
  Evaluation locks let you evaluate one of your attributes and compare the 
  result against a value stored in the lock.  The result must be an exact
  match (no wildcarding allowed, but uppercase and lowercase are considered
  to be the same).  When evaluating the attribute the enactor substitutions
  (%#/%n/etc) are replaced with information about the player trying to pass
  the lock, and 'me' and %! refer to the locked object or exit.
 
  If you call an indirect lock and the indirect lock is an evaluation lock
  (or is a compound lock that includes an evaluation lock), then the original
  lock object is checked for the attribute first, followed by the object that
  has the actual evaluation lock.  If there are multiple levels of indirection
  the intermediate locks are not checked.
 
{ 'help @lock evaluation2' for more }
& @lock evaluation2
  Examples:
    > @lock bank=checkmoney/1
    > &checkmoney bank=[gt(money(%#),5000)]
    Only people and objects with more than 5000 pennies may pass.
    Note: this lock requires wizard privileges to read the worth of other
    players.
 
    > @lock divisible_by_five_club = checkdiv/0
    > &checkdiv divisible_by_five_club = [mod(mid(%#,2,20),5)]
    Only objects whose db-number is divisible by 5 may pass.
  See also: @lock attributes.

& @lock indirect
  INDIRECT LOCKS:
 
  Key: @<object>
 
  You may reference the lock on another object and use the result of
  evaluating that other object's lock.    You pass an indirect lock if you
  pass the default lock on <object>.  This is especially useful if you
  have a large number of objects or exits that want to have the same lock,
  and you want to be able to update one object and have all the other
  locks change at the same time.
 
  <object> is searched for when you enter the @lock command and its
  database number is stored in the lock, so something like
  '@Lock north=@master.lock' is safe even if you are going to move master.lock
  to another location.
 
  Examples:
    > @lock master.lock = me
    > @lock north = @master.lock
    > @lock south = @master.lock
    North and south all reference the lock on master.lock, so you may change
    the lock on all three exits by changing master.lock.
  See also: @lock normal.

& @lock normal
  NORMAL LOCKS:
 
  Key: <object>
 
  You pass a normal lock if you either are the named object or if you carry
  the named object.  <object> may be the name or #number of a thing,  a
  playername prefixed by an asterisk (*<playername>), 'me', or 'here'.
 
  Examples:
    > @lock treasure room = secret key
    > @lock private area = me
  See also: @lock is, @lock carry.

& @lock is
  IS LOCKS:
 
  Key: =<object>
 
  You pass an is lock only if you are the named object.
 
  Example:
    > @lock mystical highway = =magic bus
    Only the magic bus may travel down the mystical highway.  You cannot
    travel the highway if you are carrying the bus.
  See also: @lock carry, @lock normal.

& @lock carry
  CARRY LOCKS:
 
  Key: +<object>
 
  You pass a carry lock if you are carrying the named object.
 
  Example:
    > @lock secret passage = +magic bus
    You can only traverse the secret passage if you are carrying the
    magic bus.  The bus cannot enter the passage on its own (perhaps
    when you are driving it).
  See also: @lock is, @lock normal.

& @lock ownership
  OWNERSHIP LOCKS:
 
  Key: $<object>
 
  You pass an ownership lock if you have the same owner as <object>.
 
  Examples:
    > @lock mystuff=$me
    Only objects you own may use the mystuff exit.
 
    > @lock/page me = !$*TinyJerk
    Neither TinyJerk nor any of his objects may page you.
  See also: @lock normal.

& @lock compound
  COMPOUND LOCKS:
 
  Key: <key> & <key>
       <key> | <key>
       !<key>
       ( <key> )
 
  You can make complex locks by combining keys with the logical AND and OR
  operators (& and ! respectively), or by using the NOT operator.  You
  may also group complex locks with parentheses.
 
  Examples:
    > @lock exit = me & !me
    An impossible lock, nothing can be both you and not you.
 
    > @lock message = me | *recipient
    Both you and the player recipient may get the message.

& @mvattr
  Command: @mvattr <object>=<old>,<new>[,<copy1>]...
  This command moves attributes around on an object.  The attribute <old> is
  renamed <new> (and is copied to <copy1>, <copy2> and so on if specified).
  If you cannot modify the <old> attribute (for instance if you are trying to
  move the Last attribute, or if it were owned by another player), then a new
  copy is made and the original is not removed.
  See also: @set.

& @name
  Command: @name <object> = <new name>

  Changes the name of <object>.  <object> can be a thing, player, exit, or
  room, specified as <name> or #<dbref> or 'me' or 'here'.
 
  See '@list options' as to whether or not a player name may contain 
  spaces.

& @notify
  Command: @notify[/<switches>] <object>[=<count>]
  Notifies the semaphore <object>, running the first command that waited on
  <object> using the '@wait <object>=<command>' or '
  @wait <object>/<time>=<command>' forms of the @wait command.  If <count> is
  specified, it indicates the number of times the semaphore is notified.
  If there are no commands (or less than <count> commands) pending for
  <object>, then subsequent @waits will not block until the semaphore count
  reaches zero again.
 
  The following switches are available:
     /first - (default) Notify the first command waiting on the indicated
              semaphore (or the first <count> commands).
     /all   - Notify all commands waiting on the semaphore and reset the
              semaphore count to zero.  <count> is ignored.
 
  See also: @drain, @ps, @wait, SEMAPHORES

& @oemit
  Command: @oemit <player>=<message>
  Emits <message> to everyone in your current location except for <player>.
  See also:  @emit, @pemit, SPOOFING.

& @open
  Command: @open[/<switches>] <direction list> [=<number>[,<direction list>]]
  Creates an exit in the specified direction(s). If <number> is specified,
  it is linked to that room. Otherwise, it is created unlinked. You or anyone
  else may use the '@link' command to specify where the unlinked exit leads.
  Opening an exit costs 1 coin. If you specify <number>, linking costs 1 more
  coin.  You can specify a second direction list (after the comma), which is 
  automatically opened in the room that the new exit goes TO and which is
  linked back to where you are.  I.e.  @open north;n=#1234,south;s
  would open exit 'north;n' from here to #1234, and an exit 'south;s'
  from #1234 to here, assuming you have rights to open exits and link to
  the rooms in question.
 
  The following switches are available:
     /location  - Create the exit in your location (default).
     /inventory - Create the exit on yourself.
 
  See also: @dig, @link, LINKING.

& @parent
  Command: @parent <object> [=<parent>]
 
  This command takes two switches, /parent and /zone. The latter switch
  only works on rooms. Rooms can take a secondary parent, which is used
  for the sole purpose of providing a secondary chain of zone checks when
  $-commands are checked.
 
  The command sets the parent of <object> to <parent> (or clears the parent
  if <parent> is omitted.  You must control <object>, and must own <parent>,
  or <parent> must be set PARENT_OK.
 
  See also: PARENT OBJECTS.

& PARENT OBJECTS
  Topic: PARENT OBJECTS
 
  Parent objects provide a way for several objects to inherit common
  attributes, exits, and $-commands from a single object, so that changing
  the parent object affects all of its children.  When searching for
  attributes or exits, first the object itself is checked, then the parent
  is checked only if the object does not have what was searched for.
 
  Any attribute the parent object has will be passed down to its children,
  if they don't already have one. For instance, if the child object has no
  description, it will inherit the description of its parent.
 
  Any exits the parent object has will show up in the exit list of the
  child, and may be used as normal exits.
 
  The parent is searched for $-commands as well as the child, unless the
  parent is uselocked against the player. The child's attributes take
  precedence over the parent's; precedence is checked by attribute name,
  NOT by $-command name.
 
{ 'help parent2' for more }
& PARENT2 
  Topic: PARENT OBJECTS (continued)
 
  A parent object may itself have a parent, up to a configurable limit
  (usually 10 levels).  The parent need not be the same type as its children,
  and flags and locks are not inherited from parent objects.  You may not
  create parent loops.
 
  See also: @parent, parent().

& @password
  Command: @password <old password>=<new password>
 
  This command changes your password.

& @pemit
  Command: @pemit[/switches] <what>=<message>
 
  Emits <message> only to <what>, or to <what>'s contents of the /contents
  switch is given.  <what> must be either in the same location as you or
  be something you own.  You can also @pemit to distant players if
  pagelocks allow you to page them, and this costs as much as a page
  <This feature is not present in all MUSHes>.  You cannot @pemit to the
  contents of something you don't own.
 
  The /list switch to this command allows you to @pemit a message to
  a list:  @pemit/list <object 1> [<object 2> <object N>] = <message>
  There can be any number of objects in the list. The objects must be
  specified by dbref number. This can be combined with the /contents
  switch.
  
  The following other switches are available:
    /contents - Send the message to the contents of the named object.
    /object   - Send the message to the named object.
    /html     - Send the message in HTML format. (Pueblo support only.)
 
  See also: page, @emit, @oemit, SPOOFING.

& @ps
  Command: @ps[/<switches>] [<object>]
  Lists information about the commands you have on each of the queues.
  Unless the /summary switch is used, this command lists all the commands you
  have on the queues, optionally along with their enactor and arguments.
  Commands scheduled to be executed at a later time (by the @wait command)
  also show the number of seconds until they will be executed and/or the
  semaphore on which they are waiting.  If <object> is specified, only
  commands run by <object> are listed, otherwise all commands run by any of
  your objects is listed.  A summary of the number of commands listed and the
  total number of commands in the queues is also displayed.  This command is
  useful for identifying infinite loops in programs.
 
  The following switches are available:
     /brief   - (default) Display a brief summary that shows the semaphore
                number, time-to-wait, object running the command, and the
                command to be run.
     /long    - In addition to the information in the /brief report, display
                the name and number of the object that caused the command
                to be run (the enactor) and the arguments to the command.
     /summary - Display just the queue counts.
 
  See also: @notify, @wait.

& @quota
  Command: @quota
  Lists your total building quota and the amount you have remaining.
  Creating objects, digging rooms, and opening exits all consume quota.
  See also: @create, @dig, @open.

& @robot
  Command: @robot <name>=<password>
  Creates a robot player owned by you.  The robot has its ROBOT flag set, so
  it may use the OUTPUTPREFIX and OUTPUTSUFFIX commands that most publicly
  available robot programs require.  This command costs 1000 coins.
  Note that some sites do not restrict OUTPUTSUFFIX and OUTPUTPREFIX to
  robots.
  See also: OUTPUTPREFIX, OUTPUTSUFFIX, ROBOT, TYPES OF OBJECTS.

& @search
  Command: @search [<player>] [<class>=<restriction>[,<low>[,<high>]]]
 
  Displays information about objects that meet the search criteria.
  Because this command is computationally expensive, it costs 100 coins.
  <player> restricts the search to the named player, while <class>
  and <restriction> control the objects listed.  Type 'help search classes'
  for a list of the classes you may use.

  Except when getting lists of players ('@search type=player' or
  '@search flags=P'), you may only search for objects that you own.
  You may limit the range of the search with <low> and <high>, which specify
  the objects to start and stop the search at, respectively.  The default for
  <low> is #0 and the default for <high> is the last object in the database.
 
  Examples:
    @search flags=PWc              <-- search for connected wizards.
    @search type=room              <-- list all rooms owned by me.
    @search eval=gt(money(##),10)  <-- search for things worth more than 10.
    @search type=room,100,300      <-- Rooms between #100 and #300, inclusive
    @search object=Test,5000       <-- Things starting with Test from object
                                       #5000 to the end of the database.
  See also: @find, search().
& @set
  Command: @set <object>=[!]<flag>
           @set <object>=<attribute>:<value>
           @set <object>=<attribute>:_<fromobj>/<fromattr>
           @set <object>/<attr>=[!]<attrflag>
 
  The first form sets (or clears) the indicated flag on <object>, the
  second form sets the <attribute> attribute on <object> to <value>,
  creating a new user-named attribute if there is no attribute named
  <attribute>.  The third form copies an attribute from another object, and
  the fourth form sets (or clears) an attribute flag on the <attr> attribute
  of <object>.
 
  When setting attributes on an object, you may also use the command
  '@<attribute> <object> = <value>' if the attribute is a predefined
  attribute.  You may also use the command '&<attribute> <object> = <value>'
  to set either predefined attributes or user-named attributes.  Either of
  these is equivalent to the second form of the @set command.
{ 'help @set2' for more }
& @set2
  The following flags may be set using the fourth form of the @set command;
  they are displayed when the attribute is examined.
 
     hidden     - Wiz-only. Prevent mortals from seeing the attribute. (M)
     html       - When used as part of an Attr/OAttr/AAtr trio (as in @verb,
                  @enter, etc.), the Attr is outputted in HTML format. (H)
     no_command - Prevent $-commands and ^-patterns defined in the attribute
                  from being performed. ($)
     no_inherit - Prevents children of the object from obtaining the 
                  attribute.  From their perspective the attribute does not
                  exist. (I)
     no_parse   - When $-commands are matched, the unparsed (non-evaluated)
                  string is used. Useful for MUSH editors. (P)
     visual     - Anyone may see the attribute when they examine you, and
                  may get the attribute with get(). (V)
     wizard     - Wiz-only. Prevent mortals from changing the attribute. (w)
 
  Unsettable: 'locked' (+) for @locked attributes; 'god' (g) and 'd' (dark)
  for attributes which can only be changed or seen by God, respectively.
 
  See also: @lock, @lock, examine, FLAGS, &.

& @stats
  Command: @stats[/all] [<player>]
  Display the number of objects in the game.  @stats/all gives a
  breakdown by object types.  If <player> is specified, the breakdown
  for the named player is given.  You may only list individual counts
  for yourself.  If invoked with no arguments or switches this command is
  free, but if you specify either /all or <player>, then this  command costs
  100 coins to run, because it is computationally expensive.
  See also: stats().

& @sweep
  Command: @sweep[/<switches>]
  This command tells you all of the objects, players, and exits that are
  listening in the room you are currently in, as well as the objects you are
  carrying.  Most objects only listen for a particular string or phrase, so
  they normally do not pose a problem if you need privacy.  You will have to 
  be careful of players, puppets, and audible exits since they will hear
  everything you say and do.  There are several switches that may be used to
  limit the type of listeners that are checked for.  They are:
     /here      - Check the room I am in.
     /inventory - Check my inventory.
     /exits     - Check exits in the room.
 
     /commands  - Check for objects that have $-commands set on them.
     /connected - Check for connected players and their puppets.
     /listeners - Check for objects with @listen set to something.
     /players   - Check for players and their puppets, whether or not they
                  are connected.
 
  The default is to search for everything.  If you specify one or more
  switches from either category (either location or listener type then only
  that location or listener type is checked.
  See also: @listen, AUDIBLE, PUPPETS.

& @switch
  Command: @switch[/<switches>] <string>=<t1>,<c1> [,<tN>,<cN>]... [,<cD>]
  Compares <string> against the targets <t1>, <t2>, etc, until a match is
  found, at which time the corresponding list of commands is performed.
  Wildcards, and the < and > operators are allowed in the targets.  By
  default, any list whose target matches the string is executed (the targets
  are not mutually exclusive). If no target matches, the default list
  <cD> is executed.
 
  The following switches are available:
     /all   - (default) Perform the actionlists associated with all targets
              that match <string>.
     /first - Perform only the actionlist associated with the first target
              that matches <string>.

& @teleport
  Command: @teleport [<object>=] <room/thing>
           @teleport [<object>=] <exit>
           @teleport [<object>=] home
 
  The first form of the @teleport command moves <object> (or you) to the named
  room or thing.  The second form sends <object> (or you) to the destination
  of the named exit, while the third form sends <object> (or you) home.
  If the destination room has a drop-to, the object will go to the drop-to
  instead of the named location.

  For the first form of the @teleport command, the object being teleported 
  must pass its location's TeloutLock; and you must control the destination,
  or it must be JUMP_OK and you must pass the destination's TportLock.
 
  The second and third forms let you remove any object from locations you
  control by sending them through an exit or to their home.
 
  See also: JUMP_OK, @lock (tport and telout), @tfail, @otfail, @atfail.

& @trigger 
  Command: @trigger[/<switch>] <object>/<attr> [=<param> [, <param>]... ]
 
  Invokes an action list stored in an attribute on an object.  The triggering
  object becomes the enactor and the positional parameters %0 through %9
  are set to the supplied parameters.  If the /quiet switch is given,
  the "Triggered." message will be omitted.
 
  See also: LOOPING.

& @unlink
  Command: @unlink <room/exit>
  This command removes drop-tos on rooms and clears the destination on exits.
  Once unlinked, an exit may be taken over by anyone with the @link command.
  See also: @link, LINKING.

& @unlock
  Command: @unlock <object>
           @unlock <object>/<attrib>
  The first form removes the lock on <object>, so that anyone may pass
  through (if an exit) or pick it up (if a player or an object).
 
  The second form clears the locked flag on the indicated attribute of the
  named object.  This allows the attribute to change ownership to the new
  owner automatically when the object is @chowned, and allows the owner
  of the object to @chown the attribute to themself or to overwrite it.
  You must own the attribute to be unlocked, but you do not need to own the
  object.
  See also: @chown, @lock, ATTRIBUTE OWNERSHIP.

& @verb
  Command: @verb <victim>=<actor>,<what>,<def>,<owhat>,<odef>,<awhat>,<args>
 
  This command provides a way to do user-defined verbs with associated
  @attr/@oattr/@aattr groups. Invoking it does the following:
  
  <actor> sees the contents of <victim>'s <what> attribute, or
    the <def> string if you can't read <victim>'s <what> attribute.
  Everyone in the same room as <actor> sees the contents of
    <victim>'s <owhat> attribute, with <actor>'s name prepended,
    or <odef>, also with <actor>'s name prepended, if you can't read
    <victim>'s <owhat> attribute.
  If you control <victim>, then he executes the contents of his <awhat>
    attribute.
  
  By supplying up to nine <args>, you may pass those values on
  the stack (i.e. %0, %1, %2, etc. up through %9).
 
  You must control the actor, but need not control the victim.  Note that
  if you don't have the ability to read the appropriate attributes (whether
  because you control the victim, he is VISUAL, or the attributes are set
  VISUAL), the default messages will be used.
 
{ 'help @verb2' for more }
& @verb2
  Here is a description of the arguments to @verb:
    victim - The object that is searched for attributes, and which runs the
             <awhat> attribute if it is found.
    actor  - The object that 'did' the verb, this is the value for %#/%n/etc
             in substitutions, and this object's name is included in the
             message to others in the same location.
    what   - The name of the attribute containing the message to be delivered
             to the actor.
    whatd  - The message to deliver to the actor if the victim does not have a
             <what> attribute, or if it cannot be read.
    owhat  - The name of the attribute containing the message (prefixed by the
             actor's name) that is sent to everyone in the room with the actor.
    owhatd - The message (prefixed by the actor's name) to deliver to others
             in the room with the actor if the victim does not have an <owhat>
             attribute, or it cannot be read.
    awhat  - The name of the attribute that is to be executed by the victim.
    args   - The comma-separated arguments to be passed for substitution
             (%0-%9).  If there is more than one argument, enclose all the
             arguments within curly braces.  Any argument that contains an
             embedded comma needs to be enclosed in curly braces as well.

    > @verb test1=me,xtest,XTEST DFLT,oxtest,OXTEST DFLT,axtest,{a,b c,de}
    You just xtested test1.
    test1 says "I was xtested. Yikes. Arg1=a, Arg2=b c, Arg3=de."
    > &xtest test1
    > @verb test1=me,xtest,XTEST DFLT,oxtest,OXTEST DFLT,axtest,{a,b c,de}

    > @fo test1={@verb test1=me,xtest,XTEST D,oxtest,OXTEST D,axtest,{a,b,de}} 
    test1 just xtested test1.
    test1 says "I was xtested. Yikes. Arg1=a, Arg2=b, Arg3=de."
  See also: locate().

& @wait
  Command: @wait <seconds>=<command>
           @wait <object>[/<seconds>]=<command>
  The first form of @wait executes <command> after <seconds> seconds.  The
  second form increments the semaphore count for <object> and executes
  <command> after <object> is notified with the @notify command.  If the
  semaphore count for <object> is negative (because it has been notified more
  times than it has been waited on), then <command> is run immediately.
  If <seconds> is specified in the second form, the command is automatically
  run after <seconds> seconds even if the semaphore isn't notified.  This
  command charges a deposit of 10 coins, which is refunded when <command>
  is executed.
  See also: @drain, @notify, @ps, SEMAPHORES.

& @wipe
  Command: @wipe <object>[/<wild-attr>]
 
  This command erases attributes from an object.  All attributes that match
  <wild-attr> (or all attributes, if <wild-attr> is not specified) are removed
  from <object>.  Attributes that you do not have permission to modify (such
  as read-only or locked attributes) are not removed.

& @aahear
  Command: @aahear <object> = <command-list>
  Attribute: Aahear
 
  An Aahear on an object is activated whenever the listen pattern
  matches anything done/said by anything else in the room, including
  itself.  (The Ahear ignores itself, helpful for keeping machines from 
  triggering itself)
 
  Example: @aahear listener = "I heard someone (maybe me?) say the word!
  See also: @ahear, @amhear, @listen.

& @aclone
  Command: @aclone <object> = <command-list>
  Attribute: Aclone
 
  Sets the actions to be taken by a new object that has just been created
  as the result of a @clone command.  The contents of the Aclone attribute
  are run by the new object and not by the old object.
 
  This attribute is only meaningful for things, and will never be
  automatically triggered on other object types.
 
  Example: @aclone Time bomb = @wait 600=@trig me/va;@wait 10=@trig me/vb
           @va time bomb = :EXPLODES with a thundering roar;@destroy me
           @vb time bomb = :ticks.; @wait 10=@trig me/vb
  See also: @clone.

& @aconnect
  Command: @aconnect <object> = <command-list>
  Attribute: Aconnect
 
  Sets the actions to be taken by a player right after connecting to the
  game.  This attribute is only meaningful for players, and will never be
  automatically triggered on other object types, with one exception.
 
  If the Global aconnects/adisconnects are executed, when a player logs
  in, any Master Room object with an @aconnect on it runs that attribute,
  with the player as the Enactor. Note that the object, NOT the connecting
  player, executes that attribute.
 
  Example: @aconnect me = check.my.mailbox
 
  See also: @adisconnect.

& @adescribe
  Command: @adescribe <object> = <command-list>
  Attribute: Adescribe
 
  Sets the actions to be taken when <object> is looked at.
 
  Example: @adesc kitten = :rubs against %n's legs affectionately.
  See also: look, @desc, @idesc, @odesc.

& @adfail
  Command: @adfail <object> = <command-list>
  Attribute: Adfail
 
  Sets the action to be taken by an object when someone tries to drop it
  but fails because they didn't pass the object's drop lock.
 
  Example: @adfail sword = @name me=Cursed Sword;:laughs maniacally.
  See also: drop, @dfail, @odfail, @lock.

& @adisconnect
  Command: @adisconnect <object> = <command-list>
  Attribute: Adisconnect

  Sets the actions to be taken by a player right after disconnecting from
  the game. This attribute is only meaningful for players, and will never be
  automatically triggered on other object types, with one exception.
  
  If the Global aconnects/adisconnects are executed, when a player logs
  out, any Master Room object with an @adisconnect on it runs that attribute,
  with the player as the Enactor. Note that the object, NOT the connecting
  player, executes that attribute.
 
  Example: @adisconnect me = home
 
  See also: @aconnect.

& @adrop
  Command: @adrop <object> = <command-list>
  Attribute: Adrop
 
  Sets the action to be taken by an object when it is dropped, or by an exit
  when it is successfully used.
 
  Example: @adrop plastique = kill %n=100; @destroy me
  See also: drop, @drop, @odrop, DROP-TO, EXITS.

& @aefail
  Command: @aefail <object> = <command-list>
  Attribute: Aefail
 
  Sets the action to be taken by an object when someone tries to enter it
  but fails because the object is not ENTER_OK or the player fails the
  object's enter lock.
 
  The enter lock only affects the 'enter' command and its aliases (set via
  the @ealias command), it does not affect exits that lead to the object or
  teleporting in.

  considered to be good building practice.
 
  Function references and %-substitutions are allowed in descriptions, and
  are evaluated when someone looks at the object.  In function references,
  'me' refers to the object being looked at, while %-substitutions that refer
  to the enactor (such as %n, %#, %p, etc) refer to the looker.

  references, 'me' refers to the object that the enactor tried to enter, while
  %-substitutions that refer to the enactor (such as %n, %#, %p, etc) refer to
  the the player who tried (and failed) to enter.
 
  The enter lock only affects the 'enter' command and its aliases (set via
  the @ealias command), it does not affect exits that lead to the object or
  teleporting in.
 
  This attribute is meaningful for players and things, and will never be
  automatically triggered on rooms or exits.
 
  Example: @efail car = The car's door is locked.
  See also: @aefail, @aenter, @ealias, @enter, @oefail, @oenter, enter,

  This attribute contains a wildcard pattern that the object listens for.
  Anything spoken, posed, emitted, or whispered in the room that <object> is
  in, as well as messages resulting from using objects (such as Opay and Succ
  messages) are checked against the Listen attribute.  When the object hears 
  something that matches the pattern, it triggers the Ahear attribute, as
  well as either the Amhear or Aahear attributes, as appropriate,
  substituting %0 the string that matched the first wildcard character in the
  Listen, %1 for the second. etc.  If the pattern in the Listen attribute is
  matched, objects in <object>'s inventory will also hear the message and
  have a chance to match it.  Objects whose Listen attribute is set to
  anything will be listed when a @sweep command is run by someone in the
  same room.
 
  If the @listen pattern is matched, then the object's contents will
  hear the message also, prefixed by the text in @inprefix if it is set.  Any
  text that matches any pattern specified in @infilter will not be sent to
  the contents.
 
  Example: @listen camera = * has arrived.

  Example: <object> @odrop stone = puts down the stone and then
                                       wipes sweat from %p brow.
           <exit>   @odrop elevator = enters the elevator from the lobby.
  See also: drop, @adrop, @drop, DROP-TO, EXITS.

& @oefail
  Command: @oefail <object> = <command-list>
  Attribute: Oefail
 
  Sets the message (prefixed by the player's name) that is shown to others in
  the same room as the player when he tries to enter the object but fails
  because the object is not ENTER_OK or the player fails the
  object's enter lock.
 
  The enter lock only affects the 'enter' command and its aliases (set via
  the @ealias command), it does not affect exits that lead to the object or
  teleporting in.
 
  This attribute is meaningful for players and things, and will never be
  automatically triggered on rooms or exits.
 
  Example: @oefail car = tries to open the car's door, but it is locked.
  See also: @aefail, @aenter, @ealias, @efail, @enter, @oenter, enter,
            ENTER_OK.

& @oenter
  Command: @oenter <object> = <message>
  Attribute: Oenter
 
  Sets the message (prefixed by the player's name) that is shown to others in
  the location being entered when someone enters <object>.  Note that the
  message is shown to those inside the object, not those outside.
 
  This attribute is meaningful for players, things, and rooms, and will never
  be automatically triggered on exits.
 
  Example: @oxenter wormhole = enters the wormhole from normal space.
  See also: enter, @aenter, @enter, @oxenter.

& @ofail
  Command: @ofail <object> = <message>
  Attribute: Ofail
 
  Sets the others failure message for <object>.  This message is seen others
  in the same location as the actor when one of these events occurs:
 
    - For exits: Someone tries to traverse the exit but cannot because they
      fail the exit's default lock or the exit is not linked.
    - For players and things: Someone tries to pick up the object but cannot
      because they fail the object's default lock.
    - For rooms, players, and things: Someone looks around inside the room,
      player, or thing and fails the object's default lock.
 
  Substitution and evaluation is performed on the message before it is shown.
 
  Examples:
    > @ofail table = tries to pick up the table, but it is too heavy.  <thing>
    > @ofail doorway = tries the knob on the door, to no avail.         <exit>
  See also: get, look, @afail, @fail, FAILURE.

& @ogfail
  Command: @ogfail <object> = <message>
  Attribute: Ogfail
 
  Sets the message (prefixed by the player's name) that is shown to others in
  the same room when someone tries to give away <object> but fails because
  they didn't pass the object's give lock.
 
  Function references and %-substitutions are allowed in give failure
  messages, and are evaluated when someone tries to give away the object.
  In function references, 'me' refers to the object being given away, while
  %-substitutions that refer to the enactor (such as %n, %#, %p, etc) refer
  to the (attempted) giver.
 
  Example: @ogfail blob = tries to give away a sticky blob of goo.
  See also: give, @agfail, @gfail, @lock.

& @okill
  Command: @okill <object> = <message>
  Attribute: Okill
 
  Sets the message (prefixed by the player's name) that is shown to others in
  the room when someone kills <object>.
 
  This attribute is meaningful for players, things, and rooms, and will never
  be automatically triggered on exits.
 
  Example: @okill guard = bashes in the guard's skull, killing him.
  See also: kill, @akill, @kill, BEING KILLED, IMMORTAL, WIZARD.

& @oleave
  Command: @oleave <object> = <message>
  Attribute: Oleave
 
  Sets the message (prefixed by the player's name) that is shown to others in
  the location being left when someone leaves <object>.  Note that the
  message is shown to those inside the object, not those outside.
 
  This attribute is meaningful for players, things, and rooms, and will never
  be automatically triggered on exits.
 
  Example: @oleave wormhole = departs the wormhole to return to normal space.
 
  See also: leave, @aleave, @leave, @oxleave.

& @olfail
  Command: @olfail <object> = <command-list>
  Attribute: Olfail
 
  Sets the message (prefixed by the player's name) that is shown to others in
  the same room as the player when he tries to leave it but fails because the
  player fails the object's leave lock.
 
  The leave lock only affects the 'leave' command and its aliases (set via
  the @ealias command), it does not affect going home, using an exit in the
  location, or teleporting out.
 
  This attribute is meaningful for players and things, and will never be
  automatically triggered on rooms or exits.
 
  Example: @olfail plane = thinks about jumping out of the plane without a
                           parachute, but wisely reconsiders.
  See also: @aleave, @alfail, @lalias, @leave, @lfail, @oleave, leave.

& @omove
  Command: @omove <object> = <command-list>
  Attribute: Move
 
  Sets the message that others in the same location see after the object has
  moved to that location from somewhere else, whether by using an exit,
  entering or leaving an object, teleporting, or going home.
 
  This attribute is meaningful for players, and things and will never be
  automatically triggered on other object types.
 
  Example: @omove car = coasts to a stop.
  See also: @amove, @move.

& @opay
  @opay <object> = <message>
  Attribute: Opay
 
  Sets the message (prefixed by the player's name) that is shown to others in
  the room when someone pays <object> enough to satisfy its Cost attribute.
 
  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.
 
  Example: @opay Coke machine = slips some change into the coin slot on the
                                Coke machine.  You hear some rumbling from
                                inside the machine and a can of Coke appears
                                in the tray at the bottom of the machine.
  See also: give, @cost, @apay, @pay.

& @orfail
  Command: @orfail <object> = <message>
  Attribute: Orfail
 
  Sets the message (prefixed by the player's name) that is shown to others in
  the same room when someone tries to give <object> a thing that does not
  pass <object>'s receive lock.
 
  Function references and %-substitutions are allowed in receive failure
  messages, and are evaluated when someone tries to give away the object.
  In function references, 'me' refers to the intended recipient of the object,
  while %-substitutions that refer to the enactor (such as %n, %#, %p, etc)
  refer to the (attempted) giver.
 
  Example: @orfail merchant = tries to unload some worthless trash on Astinous.
  See also: give, @agfail, @arfail, @gfail, @ogfail, @rfail, @lock.

& @osuccess
  Command: @osuccess <object> = <message>]
  Attribute: Osucc
 
  Sets the message (prefixed by the player's name) that is shown to others in
  the room when someone picks up the named player or thing, goes through the
  named exit, or looks at the room and passes the room's lock.
 
  Setting Osuccess messages on all takeable objects and usable exits is
  considered good building practice.
 
  Examples: <object> @osucc vase = carefully picks up the vase.
            <exit>   @osucc doorway = opens the door and leaves the room.
                                      The door closes behind %o with a click.
  See also: get, look, @asuccess, @success, SUCCESS.

& @otfail
  Command: @otfail <object> = <message>
  Attribute: Otfail
 
  Sets the message (prefixed by the player's name) that is shown to others in
  the same room when someone tries to teleport to somewhere he does not have
  permission.  You do not see this message if they couldn't teleport out of
  their present location.
 
  Function references and %-substitutions are allowed in teleport failure
  messages, and are evaluated when someone attempts to teleport to the
  specified destination.  In function references, 'me' refers to the teleport
  destination, while %-substitutions that refer to the enactor (such as %n,
  %#, %p, etc) refer to the player attempting the teleport.
 
  When a player teleports another object (@tel <object>=<destination>), the
  lock is checked against the object, not the player.
 
  Example: @otfail here = thinks about teleporting to the Magic Room, but
                          decides against it at the last moment.
  See also: @teleport, @atfail, @tfail, @lock.

& @otport
  Command: @otport <object> = <message>
  Attribute: Otport
 
  Sets the message (prefixed by your name) that others in the room to which
  the object goes see when the object teleports there.
 
  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.
  
  Example: @otport me = appears in a flash of non-wizardly brilliance.
 
  See also: @atport, @oxtport, @tport, @teleport.

& @oufail
  Command: @oufail <object> = <message>
  Attribute: Oufail
 
  Sets the message that others in the same room see when someone tries to
  use object but fails the object's use lock.  Note that the other functions
  controlled by the use lock (paying, listening, and $-commands) do not
  trigger Oufail.
 
  Example: @oufail robot = tries to activate the robot, but to no avail.
 
  See also: @aufail, @ufail, @use.

& @ouse
  Command: @ouse <object> = <message>
  Attribute: Ouse
 
  Sets the message (prefixed by the player's name) that is shown to others in
  the room when someone uses <object>.
 
  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.
 
  Example: @ouse camera = takes a picture with the camera.
  See also: use, @ause, @use.

& @oxenter
  Command: @oxenter <object> = <message>
  Attribute: Oxenter
 
  Sets the message (prefixed by the player's name) that is shown to others in
  the location being left when someone enters <object>.  Note that the
  message is shown to those outside the object, not those inside.
 
  This attribute is meaningful for players, things, and rooms, and will never
  be automatically triggered on exits.
 
  Example: @oxenter wormhole = climbs into the wormhole and vanishes.
  See also: enter, @aenter, @enter, @oenter.

& @oxleave
  Command: @oxleave <object> = <message>
  Attribute: Oxleave
 
  Sets the message (prefixed by the player's name) that is shown to others in
  the location being entered when someone leaves <object>.  Note that the
  message is shown to those outside the object, not those inside.
 
  This attribute is meaningful for players, things, and rooms, and will never
  be automatically triggered on exits.
 
  Example: @oxleave wormhole = steps out of a hyperspatial wormhole.
 
  See also: leave, @aleave, @leave, @oleave.

& @oxtport
  Command: @oxtport <object> = <message>
  Attribute: Oxtport
 
  Sets the message (prefixed by your name) that others in the room from which
  the object comes see when the object teleports out.
 
  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.
  
  Example: @oxtport me = disappears in a flash of non-wizardly brilliance.
 
  See also: @atport, @otport, @tport, @teleport.

& @pay
  Command: @pay <object> = <message>
  Attribute: Pay
 
  Sets the message that is shown to the player who gives <object> enough
  money to satisfy its Cost attribute.
 
  This attribute is only meaningful for things, and will never be
  automatically triggered on other object types.
 
  Example: @pay Coke machine = You slip some change into the slot.
  See also: give, @apay, @cost, @opay.

& @prefix
  Command: @prefix <object> = <prefix text>
  Attribute: Prefix
 
  This attribute, when set, will be used as a prefix for all text forwarded
  by the 'audible' flag on an object or exit.  The default if this attribute
  is not set is 'From <object name>,' for objects, and 'From a distance,'
  for exits.
 
  Example:
    > @fo test=out
    > @set #378=puppet
    test> test grows ears and can now hear.
    > :does something silly.
    Wizard does something silly.
    test> From a distance, Wizard does something silly.
    > @prefix out=From some strange place
    Set.
    > :does something even sillier.
    Wizard does something even sillier.
    test> From some strange place Wizard does something even sillier.
  See also: AUDIBLE, @filter, @forwardlist, @infilter, @inprefix.

& @reject
  Command: @reject <object> = <message>
  Attribute: Reject
 
  This attribute is sent as a message to anyone who tries to page you but
  you have prevented them from paging you via your page lock (@lock/page).
 
  This attribute is only meaningful for players, and will never be
  automatically referenced on other object types.
 
  Example: @reject me = I _told_ you not to page me anymore...
  See also: @away, @idle, page.

& @rfail
  Command: @rfail <object> = <message>
  Attribute: Rfail
 
  Sets the message that a player sees when he tries to give an object to
  someone else, but the receiver refuses to accept the object because
  the object didn't pass its receive lock.
 
  Function references and %-substitutions are allowed in receive failure
  messages, and are evaluated when someone tries to give away the object.
  In function references, 'me' refers to the intended recipient of the object,
  while %-substitutions that refer to the enactor (such as %n, %#, %p, etc)
  refer to the (attempted) giver.
 
  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.
 
  Example: @gfail merchant = The merchant doesn't want your worthless trash.
  See also: give, @agfail, @arfail, @gfail, @ogfail, @orfail, @lock.

& @runout 
  Command: @runout <object> = <command list>
  Attribute: Runout
 
  Sets the actions to be taken by <object> when another of its attributes is
  triggered (either automatically or via the @trigger command) and its
  Charges attribute is zero.  When this occurs, the Runout attribute is run
  INSTEAD OF the attribute that would have run normally.
 
  Example: @runout magic wand = :fizzles and turns to dust.; @destroy me
  See also: @charges.

& @sex
  Command: @sex <object> = <gender>
  Attribute: Sex
 
  Sets the gender for <object>, which is used to determine which pronouns to
  use when replacing %p, %o, %s, and %a parameters in messages that apply to
  <object>.  Genders that start with M or m are considered male, those
  starting with F, f, W, or w are considered female, those starting with
  P or p are considered plural, and anything else is considered neuter.
 
  Example: @sex me = female
           @sex me = No thank you (Silly, but possible.  Treated as neuter)
  See also: GENDER.

& @startup
  Command: @startup <object> = <command list>
  Attribute: Startup
 
  Sets a list of commands to be performed by <object> when the game is
  started up.  Typical actions include going home, cleaning visitors out of
  a room, resetting a puzzle or complex object to its initial state, or
  starting up an object that wants to run continuously.
 
  Example: @startup me = @vz me=MUSH was last restarted at [time()].
           @startup me = home

& @success
  Command: @success <object> = <message>
  Attribute: Succ
 
  Sets the message that is shown to the player who successfully picks up the
  named player or thing, goes through the named exit, or looks at the room
  and passes the room's lock.
 
  Example: <object> @succ vase = You carefully pick up the delicate vase.
           <exit>   @succ doorway = You open the door and walk through the
                                    doorway.
  See also: get, look, @asuccess, @osuccess, SUCCESS.

& @tfail
  Command: @tfail <object> = <message>
  Attribute: Tfail
 
  Sets the message that a player sees when he tries to teleport to somewhere
  he does not have permission.  You do not see this message if you couldn't
  teleport out of your present location.
 
  Function references and %-substitutions are allowed in teleport failure
  messages, and are evaluated when someone attempts to teleport to the
  specified destination.  In function references, 'me' refers to the teleport
  destination, while %-substitutions that refer to the enactor (such as %n,
  %#, %p, etc) refer to the player attempting the teleport.
 
  When a player teleports another object (@tel <object>=<destination>), the
  lock is checked against the object, not the player.
 
  Example: @tfail here = A psychic barrier prevents you from teleporting there.
  See also: @teleport, @atfail, @otfail, @lock.

& @tport
  Command: @tport <object> = <message>
  Attribute: Tport
 
  Sets the message that an object sees whenever it teleports.
  The message is displayed after the object moves to its new location.
 
  This attribute is only meaningful for players and things, and will never be
  automatically triggered on other object types.
  
  Example: @tport me = Hey! I teleported. Wow!
 
  See also: @atport, @otport, @oxtport, @teleport.

& @ufail
  Command: @ufail <object> = <message>
  Attribute: Ufail
 
  Sets the message that someone sees when they try to use object but fail
  the object's use lock.  Note that the other functions controlled by the use
  lock (paying, listening, and $-commands) do not trigger Oufail.
 
  Example: @ufail robot = The robot pointedly ignores you.
 
  See also: @aufail, @oufail, @use.

& @use
  Command: @use <object> = <message>
  Attribute: Use
 
  Sets the message that is shown to the player who uses <object>.
 
  This attribute is only meaningful for players and things, and will never
  be automatically triggered on other object types.
 
  Example: @use camera = You take a picture with the camera.  Click.
  See also: use, @ause, @ouse.

& ABODE
  ABODE  If a room is set ABODE, players can set their homes there, 
  and can set the homes of objects there.  It does not mean that a 
  player can open an exit to that room, only that they can set their 
  home there.
& AUDIBLE
  Flag: AUDIBLE(a) (all types)
 
  When set on an object, player, or room everything from a say, pose, or emit
  inside the object will be sent to every object in the location of that
  object (except for rooms which have no location) as well as to all objects
  mentioned in the object's Forwardlist attribute.  When set on an exit,
  everything from a say, pose, or emit in the room the exit is in will be
  forwarded to the room the exit points to.  In both cases the @prefix
  attribute will be inserted in front of the text, or a default prefix if no
  @prefix attribute is set.  If the @filter attribute is present, it will be
  used to suppress those messages matching any of the patterns specified.
  See also: @filter, @forwardlist, @prefix.

& BOUNCE
  Flag: BOUNCE (b)
 
  When set on an object, this flag "bounces" anything that the object
  hears to its contents (i.e., the contents hear the message also).
  This is basically equivalent to giving the object a @listen of '*'
  without an @ahear. It is, however, considerably more efficient than
  doing so, and, moreover, can be set on player objects without
  requiring the player_listen config directive to be enabled.

& CHOWN_OK
  CHOWN_OK  This flag, when set, allows you to transfer ownership to
  another player. To set it, you must be carrying the object. You 
  also have to be in the room if you want to set this flag on rooms 
  or exits.  After this flag is set, the new player may gain 
  ownership of the object by using the @chown command (See @chown).
& CONNECTED
  CONNECTED  This flag applies only to players and it shows if the 
  player is connected or not. Thus, each time you are connected to 
  the game, you should see the 'c' flag set, otherwise, you are DEAD!
  You cannot reset this flag, and it is used internally by the code 
  for things like tabulating players for the WHO list, etc.
& DARK
  DARK      If a room is DARK, then no items are shown when a person 
  'looks' there. If a thing is DARK, then "look" does not list that 
  object in the room's Contents:, and if an exit is DARK, it doesn't 
  show up in the Obvious Exits: list.  Puppets and objects that can 
  listen cannot be DARK.
& DESTROY_OK
  DESTROY_OK   When set on an object, it allows any player to destroy
  it as long as the object is not locked against them. This is good 
  for things like notes, whereby the recipient can destroy the note 
  after reading it, instead of having to look for you to destroy it.
  The DESTROY_OK flag overrides the SAFE flag, so that you do not need to
  give the /override switch to @destroy to destroy a thing that is both
  DESTROY_OK and SAFE.
  See also: @destroy, SAFE.

& ENTER_OK
  ENTER_OK   If an object or person is ENTER_OK, other players may 
  enter the object or person by using 'enter <object/person>. Players
  must also have the ENTER_OK set if they wish to be able to receive 
  things given to them by other players via the 
  'give <player> = <object>'. 
& GOING
  GOING     Used internally for the @destroy command, it is set on 
  rooms that are set to be destroyed. In the event that a player 
  decides they don't want to destroy the room after all then they can
  unset it. 
& HAVEN
  HAVEN     @set here=haven;@set me=haven. If a location is HAVEN, you 
  cannot kill in that location.  The HAVEN flag no longer blocks pages or
  @pemits, use @lock/page instead.
 
  See also: @lock/page.
& KEY
  KEY     
 
  When set on an object, it prevents non-player objects from passing
  locks on that object. Effectively, it prevents non-player objects
  from picking it up, linking to it, giving to it, etc.
 
& LINK_OK
  LINK_OK   If a room is LINK_OK, anyone can link exits to it (but 
  still not from it). It has no meaning for people, things, or exits.
  See @link.
& UNFINDABLE
  If a player is set UNFINDABLE, he cannot be found by the loc() or room()
  functions.  Bummer.
  If a room is set UNFINDABLE, players in that room (or inside objects
  in the room) cannot be found by loc()/room().

& FLOATING
  If a room is set floating, you will not be notified every 10 
  minutes or so that you have a disconnected room.
& OPAQUE
  OPAQUE   When set on a player, it prevents other players from 
  seeing what you are carrying in your inventory. Only exception is 
  when the object you are carrying belongs to the other player 
  looking at you.
& PLAYER
  PLAYER The PLAYER flag identifies you as a player. This flag cannot
  be reset by any player, not even a Wizard (not, yet, anyway 
  *grin*).  It is used mainly by the mush code to identify your 
  commands, check for validity of commands or locks etc. Generally, 
  just pretend it isn't even there.
& JUMP_OK
  When a room or thing is set JUMP_OK, then that location can be teleported
  into by anyone. See @teleport.
& PUPPET
  PUPPET   @set <object> = puppet. Causes an object to grow eyes and 
  ears, and relay all it sees and hears to its owner.  
  See: @force, PUPPETS
& ROOM
  ROOM   This flag is automatically set on rooms when you @dig a new
  room. It cannot be changed. Rooms have the added advantage that 
  they can be saved from destruction by setting the room to !GOING 
  (SEE GOING).
  However, this can only be done if no other room/object was created 
  that overwrote your room when it was set for destruction.
& VISUAL 
  VISUAL The flag a lot of players have been waiting for. When set on
  your object, it allows other players to examine it and see all the
  object's attributes as if they owned the object. They cannot make 
  any changes to the object.  This was previously called SEE_OK in
  some MUSHes.
& QUIET
  QUIET     This flag when set on yourself prevents you from hearing 
  the 'set' or 'triggered' messages from any objects you own.  When 
  set on an object, only that object will not relay its messages.
& HALTED
  HALTED    While this flag is set, the object cannot perform any mush 
  actions, listen, be triggered, etc.
& GAGGED
  GAGGED   When set on a player, it disables him from doing anything 
  except moving and looking.  He cannot talk, page, build, pose, get 
  or drop objects. (Yet another consequence of annoying the wizards.)
  Only wizards can set this flag.
& STICKY
  STICKY    If a thing is STICKY, it goes home when dropped 
  (See HOMES). If a room is STICKY, its drop-to is delayed until the 
  last person leaves (See DROP-TOs). Only meaningful for things and 
  rooms. 
& TEMPLE
  Flag: TEMPLE

  The TEMPLE flag is no longer a part of TinyMUSH.
& BUILDER
  BUILDER If a player has the BUILDER flag set, it means that all the
  building commands will work for them.  Without it, you can only 
  explore the world but not add to it. This is only settable by 
  Wizards.  Not all MUSHes use the BUILDER flag.  Some allow all players
  to build.
& WIZARD
  WIZARD    If a person is WIZARD, they are a wizard, unkillable, 
  subject to fewer restrictions, and able to use wizard commands.  
  In general, WIZARDs can do anything using #<number> or *<player>. 
  Only player #1 can set and unset the WIZARD flag of other players. 
  No WIZARD can turn their own WIZARD flag off.   
& IMMORTAL
  IMMORTAL    Objects set immortal cannot be killed and don't use up money.
  Only settable by wizards.  This is useful when an object's location
  shouldn't be changed by Joe Player, but you don't want to have to relink it
  to its current location whenever it moves.
& VERBOSE
  VERBOSE   This flag causes all commands executed by the object having
  the flag to be sent to the owner of the object.  i.e.:
  @create foo
  @set foo=VERBOSE
  @force foo="Hi.
  foo] "Hi.
  foo says "Hi."

  See also: TRACE
& INHERIT
  INHERIT   Previously, Wizard-owned objects had wizard powers.  This was
  a problem in many cases, so that behavior has changed.  Now, only Wizard
  objects or Wizard-owned Inherit-set objects have wizard powers.  Only
  players can set the Inherit flag, and the Inherit flag is reset during
  @chown.  If a player is set Inherit, all his stuff is assumed to be
  inherit, so his objects can control him.  If a player is NOT Inherit,
  his stuff does NOT control him.  (i.e. cannot @force him.)  This flag
  is not especially useful for non-wizards.
& MONITOR
  Flag: MONITOR (M)
 
  When set, anytime the object hears something from someone who passes the
  object's use lock, the object's attributes are scanned for attributes
  of the form '^<pattern>:<commandlist>'.  If the message matches the
  wildcarded <pattern>, then <commandlist> is executed, substituting %0 for
  the text that matched the first wildcard, %1 for the second, and so on.
  All matching attributes are executed, not just the first.
  Parents of MONITOR objects are never checked for ^-patterns.
 
  See also: LISTENING.
& TRACE
  Flag: TRACE(T)
 
  When a thing is set TRACE, it will report to its owner the result of all
  substitutions that it performs that change the original string.  The order
  for displaying nested evaluations (such as when evaluating the arguments to
  a function) is a site-selected configuration parameter.
 
  Example:
  > @set object = trace
  > @va object = say The result is [add(4,mul(3,%0))].
  > @trig object/va = 7
  object(#322)} '%0' -> '7'
  object(#322)} 'mul(3,%0)' -> '21'
  object(#322)} 'add(4,mul(3,%0))' -> '25'
  object(#322)} 'The result is [add(4,mul(3,%0))].' -> 'The result is 25.'
  object says "The result is 25."

{ 'help trace2' for more } 
& trace2
  When trace output is displayed in top-down order (final evaluation first,
  followed by the 'smaller' evaluations needed to perform it), then the total
  number of trace output lines that may be produced by an evaluation is limited
  to 200.  Bottom-up trace output is not limited.

  See also: VERBOSE.
& NOSPOOF
  Flag: NOSPOOF(N)
 
  This flag gives you mucho output when people @emit.  It can be annoying,
  but you'll know who's spoofing.
  See also: @emit, @femit, @oemit, @pemit.

& PARENT_OK
  Flag: PARENT_OK(Y)
 
  If an object is set PARENT_OK, then any other object that passes the object's
  ParentLock may make this object a parent of any object that it controls.
  Caution: allowing others to use your objects as parents lets them read the
  attributes on the object (as well as any parents of the object).

  See also: @lock/parent.

& LIGHT
  Flag: LIGHT(l)

  An object or exit that is set LIGHT is visible even when inside a DARK
  location.  If an object is set both DARK and LIGHT, then its contents are
  visible even though the object itself is not.

& MYOPIC
  Flag: MYOPIC(m)
 
  If you are set MYOPIC, then you are treated as if you did not own anything
  when you use the LOOK command or when you automatically look at a location
  when entering it.  Other commands (such as EXAMINE) are not affected.

& TERSE
  Flag: TERSE(q)
 
  If you are set TERSE then you are not shown the description, success/failure
  messages, contents, or exits of locations you enter.  You must use the LOOK
  or EXAMINE commands to see this information.
 
  Others in the location still get the osucc/ofail messages and the asucc or
  afail command list is still run.
 
  See also: examine, look.

& ROBOT
  Flag: ROBOT(r)
 
  If set on a player, indicates that the player is a robot and is allowed to
  use the OUTPUTPREFIX and OUTPUTSUFFIX commands that many publicly available
  robot programs require.  Some MUSHes do not restrict access to the
  OUTPUTPREFIX and OUTPUTSUFFIX commands.
 
  If set on an exit or a thing, indicates that robot players may not use the
  exit or pick up the thing, the player is treated as having failed the lock.
  See also: OUTPUTPREFIX, OUTPUTSUFFIX, @robot.

& SAFE
  Flag: SAFE(s)
 
  When set, requires the use of the /override switch to @destroy in order to
  destroy the object.  It does not prevent the destruction of the object,
  but merely requires some additional effort.  If a thing is set DESTROY_OK,
  its SAFE flag is ignored and it may be destroyed without using the /override
  switch.
  See also: @destroy, DESTROY_OK.

& TRANSPARENT
  Flag: TRANSPARENT (t)
 
  If an exit is TRANSPARENT, then when you look at it you see the description
  of the room on the other side of the exit in addition to the description
  of the exit.

& HTML
  Flag: HTML (w)
 
  If a player is set HTML, he can receive HTML output. This flag is 
  normally set by the invocation of a PUEBLOCLIENT command, and removed
  upon disconnection.
 
& SLAVE
  Flag: SLAVE (x)
 
  If set on a player, neither the player nor any of his objects may perform
  any commands that change the database.  Some sites may restrict additional
  commands.  This flag may only be set or cleared by wizards.

& CONTROL_OK
  Flag: CONTROL_OK (z)
 
  This flag doesn't do anything yet.
& STOP
  Flag: STOP (X)
 
  This flag is only settable by Wizards. If one or more $commands are
  matched on an object set STOP, no attempt will be made to match $commands
  on further objects. See 'help command evaluation' for an exact list of
  the matching order.
 
  This flag is intended primarily for use on master-room and ZONE
  local-master-room objects. The objects in the room should be 
  ordered, first to last, in order of probability of a match. Since
  master-room objects typically have many commands on them, and 
  multiple matches on the same command are not used/desired, this
  flag can save the needless computational expense of extra matching.
 
& ZONE
  Flag: ZONE (Z)
 
  When set on an object, it declares this object a "Zone". Anything
  which is parented to an object set ZONE treats that parent object like
  a local equivalent of the Master Room, provided that the configuration
  option "local_master_rooms" is turned on. To be precise:
 
  If a player types a command, and it is not an exit, built-in command,
  or $command on an object nearby, if his current location is parented 
  to something set ZONE, the contents of that parent object will be
  checked for $commands, in the same way that Master Room objects are
  (i.e. the parents of the objects in the ZONE room are not checked for
  $commands). If the ZONE object also has a parent which is set ZONE, then 
  the contents of that object will be checked, and so on. 
 
  If nothing is matched, then if his location is a room, it will check the 
  "secondary parent" (set with @parent/zone) of that room in the same manner.
  Note that the ONLY time this "secondary parent" is used is for this 
  top-level check; if it chains back through ZONE rooms, their primary 
  "normal" @parent is used.
  
  Continued in 'help Zone2'.

& ZONE2
  If nothing is matched in this way, then, if the player himself
  is parented to a ZONE object, that object's contents are checked. 
  "Secondary parents" are not checked for player zones. If still nothing 
  matches, only then will the global Master Room be checked.
 
  Most of the same caveats which apply to the global Master Room also apply
  to ZONE objects (henceforth referred to as local master rooms). The number
  of objects in the room should be kept to an absolute minimum. Objects
  which do not have $commands on them should not be placed in the room.
  Objects placed in a master room should only contain attributes with 
  $commands and other essentials (@startup, @forwardlist, and so forth);
  data attributes should be placed on another object (parenting the commands
  object to a data object is helpful, since master room checks do not
  look at the parent for $commands).
 
  Commands on objects in a local master room are run with the permissions
  of that object. This enables an area to utilize a set of $commands that
  might run with the permissions of different builders; furthermore, ZONEs
  enable a single command object to be set INHERIT, if that sort of 
  permission is needed (since simply putting $commands directly on the
  parent room causes those $commands to run with the permissions of the
  child object).

& ARBITRARY COMMANDS
  Topic: ARBITRARY COMMANDS
 
  You may define commands that are triggered whenever someone enters a command
  that matches the command template (wildcarding allowed).  These commands
  are called arbitrary commands, user-defined commands, or $-commands (for how
  they are defined), and they are checked for only after the check for
  single-character commands, exits, and internal commands have been performed
  and have failed (so an arbitrary command that matches 'page *' will never
  be performed).
 
  You define an arbitrary command by storing a string of the form
  '$<template>:<commandlist>' in an attribute of an object, then the command
  will be available to anyone who carries the object, is in the same room as
  the object, or is inside the object.  Only use user-named attributes and
  VA-VZ for arbitrary commands, as many of the predefined attributes are not
  for arbitrary commands.  <template> is the pattern to check for (it may
  contain wildcards), and <commandlist> is a semicolon-separated list of
  commands to perform.  The text that the wildcard characters matched are
  available in the variables %0 through %9.
{ 'help arbitrary2' for more }
& arbitrary2
  Example:
    > @va testobj = $foobar *:"I was foobar'ed with %0.
    Set.
    > foobar xyzzy
    testobj says "I was foobar'ed with xyzzy"
 
  You can prevent individual attributes from being checked for $-commands
  with the command '@set <obj>/<attr> = no_command'.  Attributes so set
  are reported with ($) following the attribute name when examined.
  The command '@set <obj>/<attr> = !no_command' clears the flag.
 
  The following attributes are never checked for $-commands: ALIAS CHARGES
  DESC DROP FAIL IDESC ODESC ODROP OFAIL OSUCC SEX SUCC.
 
  See also: @set.

& ATTRIBUTE OWNERSHIP
  Topic: ATTRIBUTE OWNERSHIP
  The attributes on an object may be owned independently from the object.
  Normally, the owner of the object owns all of its attributes.
  In addition to an owner, each attribute also has a locked flag,
  set or cleared with @lock <obj>/<attr> and @unlock <obj>/<attr>.
  This flag controls whether or not the owner of the object may
  @chown the attribute to himself with @chown <object>/<attrib>,
  as well as whether or not the attribute is automatically @chowned to
  the new owner when the object is @chowned.
 
  You may lock and unlock attributes that you own on any object (whether
  you own the object or not), and you may @chown an attribute that you own
  to the owner of the object if it is unlocked.  The examine command
  will show you all attributes that you own on an object, even if you
  don't own the object.
{ 'help attrib2' for more }
& attrib2
  Locked attributes may not be modified or removed, and do not change ownership
  when the object containing them is @chowned.
 
  You may not modify or remove attributes that you own that are stored
  on objects that you do not own, but you may modify or remove attributes
  owned by others on your objects (if you do this, the attribute becomes owned
  by you).
 
  If an attribute is owned by someone other than the object's owner, then
  the number of the attribute's owner is shown in parentheses immediately
  after the attribute name.  If there are any flags set on the attribute,
  those flags are indicated in the parentheses too.
 
  The + flag means means that the attribute is locked (so that it will not
  change ownership of the object is @chowned), the $ flag means that
  $-commands are not checked for that attribute.  The I flag indicates that
  the attribute is not inherited by children of the object, and the V flag
  shows that the attribute is publically visible.
{ 'help attrib3' for more }
& attrib3
 
  When checking an attribute lock against an object, the lock will always
  fail if the locked object is not owned by the same player as the attribute
  being tested.  The comparison specified in the lock is only performed if
  the owner of the locked object also owns the attribute on the object
  being checked.
 
  See also: @chown, @lock, @set, @unlock, examine.

& BEING KILLED
  Topic: BEING KILLED  
 
  Getting killed is no big deal. If you are killed, you return to your home,
  and  all things you carry return to their homes. You also collect 50 coins
  in insurance money (unless you have >= 10000 coins or you were killed via
  the Wizard slay command).  Generally, killing is not encouraged unless 
  absolutely necessary. (Note: Killing a wizard is a quick way to discover
  the many uses of the @boot command...  and killing anyone can be very
  rude.)
  See also: kill, @akill, @kill, @okill, IMMORTAL, WIZARD.

& BOGUS COMMANDS
  Topic: BOGUS COMMANDS    
  
  Bogus commands can be made using exits. For example, to make a 'sit'
  command, one could "@open sit", then "@link sit=here" (because unlinked
  exits can be stolen), "@lock sit=#0" (impossible for a room to pass a lock,
  #0 is always a room, therefore the lock always fails), and "@fail sit=You
  sit on the chair."; "@ofail sit=sits on the chair.".  Since nobody can go
  through it, it always fails. The @fail message is displayed  to the player,
  and the @ofail message (preceded by the player's name) to  everyone else.  
  See also: @afail, @fail, @link, @lock, @ofail, @open.

& BOOLEAN VALUES
  Topic: BOOLEAN VALUES
 
  Boolean values are internally considered to be either 1, generally
  interpreted as being true, and 0, which is generally interpreted as being
  false. Now, any string is interpreted as true(1), except for the null
  string (whose length is 0), which is false(0).  A #-1 is interpreted as
  false(0), and any other #<dbref> is interpreted as true(1).  Any number
  except 0 is interpreted as true(1), except 0 which is false(0). (Yes, even
  negative numbers are true(1))
 
  Examples:
  not(foo) = 0             not(<null string>) = 1   not(-66) = 0
  not(0) = 1               not(#-1) = 1             not(#12) = 0
  And so on...
 
  Note: These rules only apply when a function expects a Boolean 
  value, not for strings that expect other values.

& CONTROL
  Topic: CONTROL      
 
  There are 5 rules to controlling objects:
   1) You control anything you own.
   2) Anything you own that has its INHERIT flag set controls anything you 
      own (including you).
   3) Anything you own that does not have its INHERIT flag set only controls
      other things that you own that do not have their INHERIT flag set and
      do not control you, unless YOU have your inherit flag set.
   4) A wizard controls everything.
   5) Anybody controls an unlinked exit, even if it is locked.
 
  Builders should beware of 5, lest their exits be linked or stolen.
 
  Most of the commands for altering the database and many commands and
  functions that retrieve information only work on objects that you control.

& COSTS      
  Topic: COSTS
 
  Certain commands cost money to use, they will fail if you don't have
  enough.  Use the @list costs command to find out what these commands are
  and how much they cost.
  See also: @list.

& CREDITS
  Topic: CREDITS
 
  TinyMUSH 2.2 is a continuation of development work done on TinyMUSH 2.0.
  TinyMUSH 2.0 is derived from Larry Foard's TinyMUSH (which was itself 
  derived from TinyMUD, written by Jim Aspnes). TinyMUSH 2.0, written by
  JT Traub (Moonchilde@PernMUSH) and Glenn Crocker (Wizard@TinyCWRU),
  was a consolidation of features found in other servers, including
  TinyMUSH, PernMUSH, TinyTIM, and, later, PennMUSH.
 
  TinyMUSH 2.2 is primarily the work of Jean Marie Diaz (Ambar@PernMUSH),
  Devin Hooker (Tyleet@TwoMoons), and Lydia Leong (Amberyl@PernMUSH).
  The credits which follow are a combination of the TinyMUSH 2.0 credits
  and some additional credits for 2.2.
 
  Many, many people have contributed to TinyMUSH; our list of "thanks" is
  by no means complete.
 
  See 'help credits2' for the list of names.
 
& CREDITS2

  We would like to thank the following people:
   
  - Jim Aspnes, for the original TinyMUD (from which TinyMUSH was derived)
 
  - Larry Foard, for the original implementation of TinyMUSH.
 
  - Marcus Ranum for the original Untermud database layer code, and Andrew
    Molitor for getting it to work with TinyMUSH.
 
  - Andrew Molitor (again) for the VMS port.
 
  - Russ (Random) and Jennifer (Moira) Smith, R'nice@TinyTim, Coyote@TinyTIM,
    Ambar, Amberyl, Sh'dow, Jellan, and Miritha (all from PernMUSH),
    Javelin and Talek (from Belgariad and Dune) for numerous bug fixes, 
    enhancements, bits of code, and ideas.
 
  - Sketch(TinyTIM) for rewriting some of the more confusing help file
    entries.
 
  - Hcobb(TinyTIM) and Furie(DungeonMUSH) for inspiring the parser rewrite and
    other security-related fixes and enhancements.

& DROP-TOS
  Topic: DROP-TOS
 
  When the @link command is used on a room, it sets a drop-to location.  Any
  object dropped in the room (if it isn't STICKY) will go to that location.
  If the room is STICKY, the drop-to will be delayed until the last person in
  the room has left.
  See also: @link, STICKY.

& ENACTOR
  Topic: ENACTOR
 
  The enactor is the object that caused an action list to be performed.
  So, the enactor of the Ahear action list is the player or object who
  said/emoted/etc the message that matched the Listen attribute, the
  enactor of the Apay attribute is the player who gave the object money, etc.
  The enactor of an attribute that is run by a @trigger command is the 
  object that ran the @trigger command.  The following substitutions can be
  performed in an action list to return information about the enactor:
 
    %# or [v(#)]           - Database number of the enactor
    %N/%n or [v(N)]/[v(n)] - Name of the enactor.
    %O/%o ...              - Objective pronoun for the enactor
                             (him her it them)
    %P/%p ...              - Possessive pronoun (his her its their)
    %S/%s ...              - Subjective pronoun (he she it they)
    %A/%a ...              - Absolute possessive pronoun (his hers its theirs)
  See also: SUBSTITUTION.

& MOVING
  Topic: MOVING
 
  A number of things happen when you leave one location and enter another
  (assuming you pass the lock on the exit or have permission to enter the
  object or to teleport to the location).  The following list describes the
  actions that MUSH takes when an object moves from one place to another.
  Note that if an indicated attribute is not set, no message is displayed
  (or no action is performed).
 
  - If you are using an exit (as opposed to teleporting, entering an object,
    or going home), You receive the SUCC message for the exit, others in the
    old location receive the exit's OSUCC message, and the exit runs its
    ASUCC action list.
  - If you are teleporting or being teleported, others in the old location
    receive your OXTPORT attribute.
  - If you are a player or have your LISTEN attribute set to something,
    and if the old location is not dark and you are not dark, you receive the
    LEAVE message for the old location, others in the old location receive
    the OLEAVE message, and the old location runs its ALEAVE action list.
    Others in the new location receive the OXENTER message from the old
    location, and others in the old location receive the message '<yourname>
    has left.'
{ 'help moving2' for more }
& moving2
  - You are moved to the new location.  If you are entering an object,
    teleporting, or going home, all KEY objects are stripped from you.
  - If the new location is a room, you receive the room's DESC, others in the
    room receive the ODESC, and the room runs its ADESC.  If you pass the
    room's lock do the same with SUCC, OSUCC, and ASUCC, otherwise use FAIL,
    OFAIL, and AFAIL.
  - If the new location is a player or an object, you receive the location's
    IDESC (or DESC if the IDESC is not set).  In either event, others in the
    same location see the ODESC message and the location runs its ADESC 
    action list.
  - You are shown the contents and visible exits if the location is not DARK.
  - If you used an exit, then you receive the DROP message for the exit,
    others in the new room receive the exit's ODROP message, and the exit
    runs its ADROP action list.
  - If you are teleporting or being teleported, you receive your TPORT
    attribute, others in your new location receive your OTPORT attribute,
    and your ATPORT attribute is run.
  - You receive your MOVE attribute, others in your new location receive
    your OMOVE attribute, and your AMOVE attribute is run.
{ 'help moving3' for more }
& moving3
  - If you are a player, or have your LISTEN attribute set to something,
    and if the old location is not dark and you are not dark, you receive the
    ENTER message for the new room, others in the new room receive the OENTER
    message, and the new room runs its AENTER action list. Others in the room
    you just left receive the new room's OXLEAVE message, and others in the
    old location receive the message '<yourname> has arrived.'
  - If the old location is a STICKY room and has its drop-to set, see if
    objects in that room should be sent to the drop-to location.  If so,
    do it.
  - If you are a player, you have a chance of finding some money.

& EXITS
  Topic: EXITS
 
  An exit links one location to another location, providing a way to travel
  on the MUSH.  Although normally used to link rooms together, exits can be
  made to and from players and objects.
 
  You may pick up exits that you own, and drop exits into locations that
  you own.  When you pick up or drop an exit, anyone in the exit's new
  location may use the exit and travel to its destination.
 
  If an exit is set DARK it will not show up in the list of obvious exits in
  a room.
  See also: @link, @open.

& FAILURE
  Topic: FAILURE  
 
  You fail to use a player or a thing when you cannot take it (because it's
  lock fails).  You fail to use an exit when you cannot go through it
  (because it is unlinked or locked). You fail to use a room when you fail
  to look around (because it's locked).
  See also: get, look, @afail, @fail, @lock, @ofail, STRINGS.

& FLAGS
  Topic: FLAGS
 
  Everything in the universe of this MUSH (Rooms, Exits, Things, Players,
  etc) are represented in the same way at the program level.  A room merely
  has the room flag set and a player has the player flag set.  In addition,
  flags also give objects abilities or qualities.  For instance, a wizard
  has the wizard flag set.  That is what lets the program know he may use
  wizard abilities.  An object or room may have the dark flag set. In the
  case of an object, this makes the object invisible to normal eye-sight.
  In the case of a room, the room becomes too dark to see other objects or
  players.  To get a list of the flags that are available, type '@list flags'
  or 'help flag list'. For more specific information on a particular flag,
  request help on the flag's name, as in 'help ENTER_OK'.

& FUNCTIONS
  Topic: FUNCTIONS
 
  Functions are specialized commands used to manipulate strings and other
  input. The format for a function is of this form: [fun-name(<input>)]
  Although usually the []'s indicate an input that is optional, in this case
  they are necessary and tell the MUSH that this is a function, although
  nested functions (like [first(rest(This is a nice day))] returns 'is') do
  not require more than one pair of []'s.  Nested brackets may be used when
  it is necessary to insert a function call in the middle of an argument,
  like [get(me/[get(me/vz)])], which returns the contents of the attribute
  named in the VZ attribute.
 
  For help on a particular function, type 'help <functionname>'.  You may
  need to include the parentheses with the function name, ie.
  'help <functionname>()'.  Type 'help function list' or '@list functions'
  for a list of the available functions.  'help function classes' will show
  a list of the functions broken down into classes.

& GENDER
  Topic: GENDER
 
  A player's (virtual) gender is specified in the Sex attribute.  This
  attribute controls how gender-specific pronoun substitutions are evaluated
  for the player.  If the player's Sex attribute starts with an 'M' or an 'm'
  then the player is assumed to be male,  'F', 'f', 'W', and 'w' indicate
  female, and anything else indicates neuter.
  See also: SUBSTITUTIONS.  

& GOALS
  Topic: GOALS
 
  There is no ultimate goal to this game, except to have fun.  There are
  objects and places to build, puzzles to solve, scenery to visit, and people
  to meet. There are no winners or losers, only fellow players.  Enjoy.

& HERE
  Topic: HERE 
 
  The word 'here' refers to the room you are in (if you are inside an object,
  it refers to the object that you are in, not the room that the object is
  in).  For example, to rename the room you are in (if you control it), you
  could enter '@name here= <new name>'.

& HOMES
  Topic: HOMES
 
  Every thing or player has a home.  This is where players when they go home,
  or things with the STICKY flag set go when dropped.  Homes are set with the
  @link command. A thing's home defaults to the room where it was created, if
  you control that room, or your home. You can link an exit to send players
  home with '@link <dir>=home'.  Drop-tos can also be set to 'home'.
  See also: @link, DROP-TO, STICKY.

& LINKING  
  Topic: LINKING
 
  You can link to a room if you control it, or if it is set LINK_OK or ABODE.
  Being able to link means you can set the homes of objects or yourself to
  that room if it is set ABODE, and that you can set the destination of exits
  to that room if it is LINK_OK.
  See also: @link, ABODE, LINK_OK.

& LISTENING
  Topic: LISTENING
 
  Thee are two ways to listen for something in a room. The easiest way
  is to use a combination of @listen and @ahear/@aahear/@amhear. The
  second way is to use a "^" pattern in an attribute, similar to the way
  "$" is used for user-defined commands. The attribute takes the form:
  '^<pattern>:<action>'.
 
  The ^-pattern check is only performed on objects with their MONITOR flag
  set.  The criterion for triggering a pattern-listen is the same as that for
  triggering an @ahear - the object cannot trigger its own listen patterns.
  All matching attributes have their <action>s performed, not just the first.
  Also, attributes with the no_command flag set are not checked for ^-patterns,
  and neither are objects' parents.
 
  Example:
    > @va test = ^* says "foo *":say I got a foo with %1!.
    Set.
    > @set test=monitor
    test grows ears and can now hear.
    > say foo bar
    You say "foo bar"
    test says "I got a foo with bar!."
  See also: @ahear, @listen, @set.

& LISTS
  Topic: LISTS
 
  A list is a string, usually stored in an attribute (currently any of the
  va-vz attributes), which is a series of words, separated by one or more
  spaces.  The following would be a list (denoted on the ends by ', which is
  not actually in the string): 'one two three four five'.  The functions
  first(), rest(), cat(), member(), and remove(), all work on lists.
 
  See also: cat(), first(), member(), remove(), rest().

& LOOPING
  Topic: LOOPING
 
  Looping in an object can have its good parts and its bad parts.  The good
  part is when you activate part of a program multiple times to exhaustively
  perform an operation.  This is usually done by:
     @va object =  <list of commands>;@trigger me/vb
     @vb object =  @switch <test> = <false>,@trigger me/va,<otherwise go on>
 
  Looping can be a problem when it goes on without stopping.  The @ps command
  can be used to see if you are looping.  Beware!  A looping machine that
  isn't @halt'ed will drain your money supply while you are away!
  See also: @halt, @ps.

& ME
  Topic: ME
 
  The word 'me' refers to yourself. Some things to do when starting out: 
 
  1) Give yourself a description with 
     '@desc me = <description>', then look at yourself with 'look me'.
 
  2) Set your gender, if you wish it known, with
     '@sex me=male' or '@sex me=female'  (or '@sex me=neuter' to be an 'it').
 
  3) Prevent other people from picking you up, with '@lock me=me'
 
  4) Let other people give you money, but not jump into you, with
     '@lock/enter me=me' and then '@set me=ENTER_OK'
 
  5) Prevent other people from using you, with '@lock/use me=me'
 
& MONEY
  Topic: MONEY
 
  You need money to build within the game, to run programmed objects or use
  certain other commands, or to buy things from vendors set up by other
  players.  You can get money via one or more of these methods:
    1.  You receive a daily allowance for each day you connect.
    2.  You have a chance of finding money as you wander around areas that
        other people have built.
    3.  Some MUSHes may implement a place where you can sell valuable objects
        for money.
  See also: @list costs, COSTS.

& PUPPETS
  Topic: PUPPETS
 
  An object is made into a puppet by doing '@set <object>=puppet', once an
  object is a puppet it will relay all that it sees and hears to its master.
  All objects created by a puppet are owned by its master, when puppets spend
  or earn money, they use their master's money supply.  In order to prevent
  puppets from screwing up puzzles, objects may have the KEY flag set, this
  will prevent puppets from picking the object up. A puppet may be commanded
  by its master by '@force <object>=command', or by the shorthand version, 
  '#<number of puppet> command'.  The puppet flag is handy for debugging, as
  it allows you to see the result messages your object generates.
 
  Example:       
  @force fred="hi there.  -or-  #4342 "hi there.
  See also:  VERBOSE.

& ROBBERY
  Topic: ROBBERY
 
  Robbing is not allowed on this MUSH. If you really need money, ask your
  friendly neighborhood wizard.
  See also: MONEY.

& search classes
  Topic: SEARCH CLASSES
 
  You may use the following classes in @search commands and search()
  function calls:
  
  TYPE      - Restricts to objects of the indicated type (OBJECTS, ROOMS,
              EXITS, PLAYERS).  THINGS may be used as an alias for OBJECTS.
  NAME      - Restricts to objects whose names start with <restriction>.
  OBJECTS   - A combination of TYPE=OBJECT and NAME=<restriction>.
  THINGS    - An alias for OBJECTS.
  ROOMS     - A combination of TYPE=ROOM and NAME=<restriction>.
  EXITS     - A combination of TYPE=EXIT and NAME=<restriction>.
  PLAYERS   - A combination of TYPE=PLAYER and NAME=<restriction>.
  FLAGS     - Restricts to objects which have the flags listed in
              <restriction> set..
  EVAL      - Evaluates the restriction for each object, replacing ##
              with the object's database number.  Evaluations that return
              TRUE (ie, not 0 or #-1) are selected.
  EOBJECT   - A combination of TYPE=OBJECT and EVAL=<restriction>.
  ETHING    - An alias for OBJECTS.
  EROOM     - A combination of TYPE=ROOM and EVAL=<restriction>.
  EEXIT     - A combination of TYPE=EXIT and EVAL=<restriction>.
  EPLAYER   - A combination of TYPE=PLAYER and EVAL=<restriction>.

& SEMAPHORES
  Topic: SEMAPHORES
 
  Semaphores may be used for synchronizing complex objects or for enforcing
  mutual exclusion.  You may use any object you own or any LINK_OK object as
  a semaphore, and any type of object (thing, room, player, or exit) may be
  used.
 
  The semaphore state of an object is shown by the Semaphore attribute (which
  is read-only); a positive number indicates the number of commands awaiting
  notifies, and a negative number indicates the number of waits on that
  semaphore that will not block.
 
  Use the '@wait <object>' form of the @wait command to request a command be
  delayed until <object> is notified with the @notify command.  The @drain
  and @notify/all commands clear the semaphore on <object>, either
  discarding or executing all pending commands.  Remember that the
  object performing the @wait executes the command, not the object used
  as a semaphore. 
{ 'help semaphores2' for more }
& semaphores2
  You may also combine the semaphore and timer options of @wait with
  '@wait <object>/<timeout> = <command>'  If the time period expires before
  the semaphore is notified, then the command is executed and the semaphore
  count is decremented, just as if the command had been run because the
  semaphore had been notified.
 
  Examples: <simple>     @wait semaphore="Foo
                         @notify semaphore
            <mutex lock> @va mutex lock=@wait me=@trig me/vb
                         @vb mutex lock="Got it!;@notify me
                         @startup mutex lock=@notify me
            <timed wait> @wait timer/60 = "Sixty Second Timer.
 
  In the above examples you will say "Foo" after semaphore is notified,
  you will say "Got it" when you have the mutual exclusion lock mutex lock
  (You could have also modified object registers that need to be protected
  from concurrent update), and you will say "Sixty Second Timer." either when
  timer is notified or after sixty seconds pass.
 
  See also: @drain, @notify, @wait.

& SPOOFING
  Topic: SPOOFING
 
  Spoofing is the act of making other characters think that a person said or
  did something that they did not.  This is very easy to accomplish, and has
  some good effects, which is why it is allowed.  Note that the NOSPOOF flag
  allows players to see exactly who is spoofing what.
 
  Example:
    ... From TinyJerk's perspective ...
    > @emit Wizard is a jerk!
    Wizard is a jerk.
 
   ... From Wizard's perspective, Wizard is set NOSPOOF ...
   [TinyJerk(#226)] Wizard is a jerk!
   > @boot tinyjerk
   You booted TinyJerk off!
   TinyJerk has disconnected.
   1 connection closed.
 
   ... TinyJerk's perspective again ...
   Wizard gently shows you the door.
 
   *** Disconnected ***

& STACK
  Topic: STACK
 
  Command lists that are run on objects can have up to 10 stack values
  named %0 through %9 (or [v(0)] through [v(9)]).  Stack values can be set
  by the @trigger command, or by matching wildcard characters in the Listen
  attribute (in the case of the Ahear, Aahear, and Amhear attributes).
 
  Example:
    > @listen item = * foo *
    Set.
    > @ahear item = "-->[v(1)]<-- bar -->[v(0)]<--
    Set.
    > say Fee fie foo fum
    You say "Fee fie foo fum"
    item says "-->fum"<-- bar -->Wizard says "Fee fie<--"

& SUBSTITUTIONS
  Topic: SUBSTITUTIONS
 
  All messages may contain %-substitutions, which evaluate to gender-specific
  pronouns if the player's gender is set or to other useful information.
  Information returned is based on the player that caused the message to be
  displayed, not the object that stored the message or which is running the
  action list.  The substitutions available are:
 
    %s, %S  = Name, he, she, it, they.        (subjective)
    %o, %O  = Name, him, her, it, them.       (objective)
    %p, %P  = Name's, his, her, its, their.   (possessive)
    %a, %A  = Name's, his, hers, its, theirs. (absolute possessive)
    %n, %N  = the player's name.
    %r      = carriage return
    %t      = tab character
    %b      = space character
    %%      = literal '%' character
    %0-%9   = Value of positional parameter/stack location 0 through 9.
    %va-%vz = Contents of attribute va through vz
    %#      = Database number of the object that caused the message to be
              displayed or the action list to be run.
{ 'help substitutions2' for more }
& substitutions2
    %l      = Database number of the location of the object that caused the
              message to be displayed or the action list to be run.
    %!      = Database number of the object holding the message or running
              the action list.
    %c      = Text of last command executed.
 
  If the letter following the % is capitalized, the first letter of the
  result of the substitution is also capitalized.
 
  Note: %<whatever> is equivalent to [v(<whatever>)], but is more efficient.
  See also: GENDER, V().

& SUCCESS
  Topic: SUCCESS
 
  You successfully use a player or a thing when you take it (because you
  passed the lock).  You successfully use an exit when you go through it.
  You successfully use a room when you look around and the room is not locked
  against you.
  See also: get, look, @asuccess, @lock, @osuccess, @success.

& SWITCHES
  Topic: SWITCHES
 
  Some commands have command switches associated with them that can be used
  to modify their behavior.  For instance, switches on the @ps command
  control the amount of information displayed, and switches on the @switch
  command indicate whether to perform all actionlists whose targets match
  the search string, or just the first.
  See also: @list.

& OBJECT TYPES
  Topic: OBJECT TYPES
 
  There are 4 types of objects: things, players, exits, and rooms. The first
  letter following an object's ID number indicates the type: P(layer),
  E(xit), R(oom), otherwise, thing.  Things are inanimate objects that can
  be carried.  Players are animate objects that can move and carry. Exits
  are the means by which objects move from room to room. Rooms are locations
  that contain objects and linked exits.

& COMMAND EVALUATION
  Topic: COMMAND EVALUATION
 
  When you submit a command to be executed by MUSH (whether by typing it in or
  by having a machine run it, the following steps are performed, in sequence.
  If the command matches something in a step, the matching actions are
  performed and the walk down the list stops.
 
  - If the command was typed in, it is checked against the uppercase-only
    commands (QUIT, WHO, etc).  If so, the command is executed.
  - The first letter of the command is checked to see if it is a single-
    character command (", :, etc).  If so, %-substitution and function
    evaluation may be performed (depending on the command), and the command
    is executed.
  - The command is checked to see if it is the 'home' command.  If so, the
    player or object performing the command goes home.
  - The command is checked against the exits in its current room.  If one
    matches, it is performed.  If more than one matches, one is picked randomly
    from the exits for which the player passes the lock (If the player does not
    pass any locks, then the exit to be tried is picked randomly.
{ 'help command evaluation2' for more }
& command evaluation2
  - The first word of the command is checked to see if it is an internal MUSH
    command.  If so, the remainder of the command is broken up into arguments,
    %-substitution and function evaluation may be performed on the (split up)
    arguments, and the command is executed.
  - %-substitution and function evaluation is performed on the command.
  - The player himself (if self-command matches are configured), objects 
    in the player's location, the player's location itself, and objects in
    the player's inventory, in that order, are searched for $-commands 
    that match the command. All that match are performed, unless a match
    was made on a STOP-set object (see 'help STOP').
 
  Note: Commands that can cause other commands to be executed (such as @wait,
  @switch, @trigger, etc) never perform substitution on their arguments, they
  leave the evaluation to the command that is to be executed.  This prevents
  most of the problems with getting objects to perform unintended commands by
  putting a ';', '}', or ',' in an argument.  The @force command is an
  exception in that it evaluates its argument, so it should be used with
  caution (preferably by never using it to pass information that someone else
  entered, use @trigger instead).
 
  Also, the construct '$xx *:%0' does not work (and is very dangerous
  programming), use '$xx *:@force me=%0' if you need this functionality.

& VERBS
  Topic: VERBS
 
  For many verbs there are three attributes that specify messages and actions
  associated with the verb in addition to the verb's builtin action.
  The attributes are named Verb, Overb, and Averb.  Verb is the message that
  the enactor sees, Overb is the message that everyone else in the same room
  as the enactor sees, and Averb is a list of commands that are run.
  These attributes may be set using the @<attribute> command, so the commands
  to set the attributes related to the 'drop' command are @drop, @odrop, and
  @adrop.

& WIZARDS
  Topic: WIZARDS
 
  Wizards are the people that help run the game and make sure that everything
  is working properly.  They have special powers to tweak reality in ways
  mortals can only dream of.  Be nice to them, they are going out of their
  way to help keep the game running smoothly.

& V()
  Function: v(<string>)
  The V function can be used as an alternative for percent (%) substitution
  and also as a replacement for get(me/<arg>).  If the argument is two
  characters long or longer and starts with a letter, then the object
  performing the v() call (and its parent, if necessary) is searched for the
  named attribute, and its value is returned if possible.  Otherwise, a
  percent substitution is performed on the argument (so that v(o) is
  equivalent to %o, for instance).  The percent form (%o in the previous
  example) is preferred as it is faster, and there are no longer any security
  problems associated with it.  Note that attributes with single-character
  names cannot be retrieved with v().
  See also: GENDER, SUBSTITUTION, PARENT OBJECTS.

& wordpos()
  Function: wordpos(<string>, <charpos>[, <delim>)
 
  Returns the number of the word within <string> where the character position
  <charpos> falls.  Spaces between words are treated as belonging to the word
  that follows them.  If <charpos> is not within the string, the value #-1 is
  returned.  Both words and characters are numbered starting at 1.
 
  <delim> may be used to specify a delimiter other than a space.
 
  Example:
    > say wordpos(This is a test, 4)
    You say "1"
    > say wordpos(This is a test, 5)
    You say "2"
    > say wordpos(This is a test, 6)
    You say "2"
    > say wordpos(This is a test, 20)
    You say "#-1"

& type()
  Function: type(<object>)
  Returns a string indicating the object type of <object>, either EXIT,
  PLAYER, ROOM, or THING.
 
  Example:
    > say type(me)
    You say "PLAYER"
    > say type(here)
    You say "ROOM"

& hasflag()
  Function: hasflag(<object>[/<attribute>],<flag>)
 
  Returns true if object <object> has the flag named <flag> set on it.
  You may not be able to retrieve information for objects that you do not
  own.
 
  With an object-attribute pair, this can also be used to check for the
  attribute flags "dark", "hidden", "html", "visual", "no_command", 
  "no_inherit", "no_parse", "locked", "wizard", and "god".
  
  Example:
    > say hasflag(me, wizard)
    You say "0"
    > say hasflag(me, connect) 
    You say "1"

& ANDFLAGS()
  Function:  andflags(<object>,<list of flags>)
 
  This function returns 1 if <object> has all the flags in a specified list,
  and 0 if it does not. The list is specified with a single letter standing
  for each flag, like the output of the FLAGS() function. A '!' preceding
  a flag letter means "not flag".
 
  Thus, ANDFLAGS(me,WD) would return 1 if I was set WIZARD and DARK.
  ANDFLAGS(me,W!Dc) would return 1 if I was set WIZARD, not DARK, and
  CONNECTED.
 
  If a letter does not correspond to any flag, <object> doesn't have it,
  so the function returns 0. There can be an arbitrary number of flags.
  Do not put spaces between flag letters.
 
  See also:  hasflag(), orflags()

& ORFLAGS()
  Function: orflags(<object>,<list of flags>)
 
  This function returns 1 if <object> has at least one of the flags in a
  specified list, and 0 if it does not. The list is specified with a 
  single letter standing for each flag, like the output of the FLAGS()
  function. A '!' preceding a flag letter means "not flag".
 
  Thus, ORFLAGS(here,JA) would return 1 if my location is set JUMP_OK
  or ABODE. ORFLAGS(me,D!c) would return 1 if I am DARK or not CONNECTED.
 
  If a letter does not correspond to any flag, <object> doesn't have it,
  so it is simply ignored. There can be an arbitrary number of flags. Do
  not put spaces between flag letters.
 
  See also:  hasflag(), andflags()

& delete()
  Function: delete(<string>,<first>,<len>)
  Returns <string>, but with <len> characters starting after the character
  at position <first> removed.  In other words, this function copies <first>
  characters, skips <len> characters, and then copies the remainder of the 
  string.
 
  Example:
    > say delete(abcdefgh, 3, 2)
    You say "abcfgh"
    > say delete(Would you like coffee or perhaps tea?, 15, 18)
    You say "Would you like tea?"

& lock()
  Function: lock(<object>[/<whichlock>])
 
  Returns the named lock on <object>.  If you don't specify the lock to get,
  the default lock is returned.  You must control <object>.

& elock()
  Function: elock(<object>[/<whichlock>],<victim>)
  Checks if <victim> would pass the named lock on <object>.  Only the object's
  owner may test locks other than the default lock.

& LWHO()

  Returns a list of the db numbers of connected players.
 
  Example:
    > WHO
    Player Name          On For Idle  Doing
    Mortal                00:11   0s  
    Evinar                00:12   6m  
    Wizard                00:32   6s  
    3 Players logged in.
    > say lwho()

  See also: WHO, conn(), idle().

& OBJ()
  Function: obj(<object>)
 
  Returns the proper objective pronoun (him, her, it, them) for referring to
  <object>, based on the object's Sex attribute.  You must either control
  or be near <object>.

& POSS()
  Function: poss(<object>)
 
  Returns the proper possessive pronoun (his, her, its, their) for referring
  to <object>, based on the object's Sex attribute.  You must either control
  or be near <object>.

& APOSS()
  Function: aposs(<object>)
 
  Returns the proper absolute possessive pronoun (his, hers, its, theirs) for
  referring to <object>, based on the object's Sex attribute.  You must either
  control or be near <object>.

& SUBJ()
  Function: subj(<object>)
 
  Returns the proper subjective pronoun (he, she, it, they) for referring to
  <object>, based on the object's Sex attribute.  You must either control
  or be near <object>.

& NEARBY()
  Function: nearby(obj1,obj2)
 
  Tests if obj1 is near obj2 (if it is in the same location, in obj2's
  inventory, or is obj2's location).  You must control either obj1 or obj2, or
  be near either one of them, if both of these tests fail then 0 is returned.
  This function returns 1 if the two objects are nearby and 0 if not.

& GET()
  Function: get(<object>/<attribute>)
 
  The get function fetches the specified attribute from the named object.
  It can be used to get attributes from objects you own, public and visual
  attributes of objects near you, and public and visual attributes other
  than the description of players wherever they may be.  If the attribute is
  not present on <object>, its parent is searched for the attribute.
 
  Example:
    > read me
    > say get(me/desc)
  See also: get_eval().

& GET_EVAL()
  Function: get_eval(<object>/<attribute>)
 
  The get_eval function returns the specified attribute from the named object
  (just like the get function), except that function references and
  %-substitutions have already been performed.  In function references, 
  'me' refers to the object being looked at, and %-substitutions that refer
  to the enactor (such as %n, %#, etc) refer to the object making the get_eval
  call.  If the attribute is not present on <object>, its parent is searched
  for the attribute.
 
  Example:
    > @va test = This is a get_eval test on %n.  The vb is [get(me/vb)]
    > @vb test = VB from test
    > @vb me = VB from me
    > say get(test/va)
    You say "This is a get_eval test on %n. The vb is [get(me/vb)]"
    > say get_eval(test/va)
    You say "This is a get_eval test on Foobar. The vb is VB from test"
  See also: get().

& DEFAULT()
  Function:  default(<obj>/<attr>,<default case>)
 
  This function returns the value of <obj>/<attr>, as if retrieved via
  the get() function, if the attribute exists and is readable by you.
  Otherwise, it evaluates the default case, and returns that.
  Note that the default case is only evaluated if the attribute does
  not exist or cannot be read.
 
  This is useful for code that needs to return the value of an attribute,
  or an error message or default case, if that attribute does not exist.
 
  Examples:
    > &TEST me=apple orange banana
    > say default(me/Test, No fruits!)
    You say "apple orange banana"
    > &TEST ME
    > say default(me/Test, No fruits!)
    You say "No fruits!"
 
  See also:  get(), get_eval(), u(), edefault(), udefault().
 
& EDEFAULT()
  Function:  edefault(<obj>/<attr>,<default case>)
 
  This function returns the evaluated value of <obj>/<attr>, as if
  retrieved via the get_eval() function, if the attribute exists and
  is readable by you. Otherwise, it evaluates the default case, and
  returns that. The default case is only evaluated if the attribute
  does not exist or cannot be read.
 
  Example:
    > &TEST me=You have lost [rand(10)] marbles.
    > say edefault(me/Test,You have no marbles.)
    You say "You have lost 6 marbles."
    > &TEST me
    > say edefault(me/Test,You have no marbles.)
    You say "You have no marbles."
  
  See also:  get(), get_eval(), u(), default(), udefault().
 
& UDEFAULT()
  Function:  udefault([<obj>/]<attr>,<default case>[,<arg>]...)
 
  This function returns the value of the user-defined function
  as defined by <attr> (or <obj>/<attr>), as if retrieved via
  the u() function, with <args>, if the attribute exists and is
  readable by you.
 
  Otherwise, it evaluates the default case, and returns that. The
  default case is only evaluated if the attribute does not exist
  or cannot be read.
 
  Examples:
    > &TEST me=[center(%0,5,*)]
    > say udefault(Test,-- BOOM --,ACK)
    You say "*ACK*"
    > &TEST me
    > say udefault(me/Test,-- BOOM --,ACK)
    You say "-- BOOM --"
 
  See also:  get(), get_eval(), u(), default(), edefault().

& TIME()
  Function: time()
 
  Gives you the current time.
  WARNING!  This is the time on the machine that the mud is running on, and
  not where you are.
 
  Example:
    > say time()
    You say "Thu Dec 19 09:48:06 1991"
  See also: convsecs(), convtime(), secs().

& RAND()
  Function: rand(<num>)
 
  Rand returns an integer between 0 and num-1.
 
  Example:
    > say rand(10)
    You say "6"
    > say rand(10)
    You say "1"
    > say rand(10)
    You say "4"
    > say rand(10)
    You say "9"
    > say rand(10)
    You say "1"

& EXIT()
  Function: exit(<object>)
 
  Exit returns the first exit on the list of exits in the object.  Dark exits

    You say "List"
  See also: rest(), last().

& REST()
  Function: rest(<string>[, <delim>])
 
  The rest function takes a string, returns all the string except the first
  word, that is, everything to the right of the first space, or an empty 
  string, or the empty string if there are no spaces in the string.  
 
  <delim> may be used to specify a word delimiter other than a space.
 
  Example:
    > say rest(This is a test) 
    You say "is a test"
    > say rest(Would you like coffee, or perhaps tea) 
    You say "you like coffee, or perhaps tea"
    > say rest(List!with!different!delimiters,!)
    You say "with!different!delimiters"
 
  See also: first(), last().

  Example:
    > say last(This is a test)
    You say "test"
    > say last(Happy-Fun-Test-Thing,-)
    You say "Thing"
 
  See also:  first(), rest().

& LASTCREATE()
  Function: lastcreate(<object>, <type>)

  Returns the dbref of the last object of <type> that was created by
  <object>. You must control <object>.
 
  In general: If <type> is 'R', it will be the dbref of the object's most
  recent @dig. If it is 'E', it will be the dbref of the object's most 
  recent @open. If it is 'T', it will be the dbref of the object's most
  recent @create. If it is 'P', it will be the dbref of the object's
  most recent @pcreate.
 
  Note that @clone will set the 'most recent' in accordance with the
  type of the object being cloned.

& OBJMEM()
  Function: objmem(<object>[/<attribute pattern>])
 
  Returns the number of bytes of memory consumed by attribute text on an 
  object. If an attribute wildcard pattern is specified, only those 
  attributes will be counted. You must be able to read an attribute in
  order to check its size.
 
& STRLEN()
  Function: strlen(<string>)
 
  Returns the number of characters in <string>.
 
  Example:
    > say strlen(This is a test)
    You say "14"
    > say strlen(Would you like coffee, or perhaps tea)
    You say "37"

& MID()
  mid(<string>, <first>, <length>)
 
  Mid returns a segment of the string, the <length> characters to the
  right of the <first> character.  Note that the first character in a
  string is numbered zero, and not one.

& COMP()
  comp(<string1>, <string2>)
 
  Comp compares two strings.  It returns 0 if they are the same, 1 if
  string2 is less than/precedes alphabetically string1, and -1 
  otherwise.
& S()
  s(string)
 
  This function performs pronoun substitution in a string, and then returns
  that string.  As usually, %n is the name, %s the subjective pronoun, %o the
  objective, %p the possessive, and %a the absolute possessive.  It is
  important to note that the pronoun is that of the triggering object.
 
  So, if the ve of an object were: "[s(This is %n)], and I were to 
  type @trigger <object>/ve, it would return "This is <myname>", but 
  if vf were @trigger me/ve, then triggering the vf makes the ve 
  return "This is <object>"

& LEFT()
  Function: left(<string>, <number>)
 
  This function returns the first <number> characters from the left-hand
  side of <string>.
 
  Example:
    > say left(flipper,3)
    You say "fli"
 
  See also: right(), mid()

& RIGHT()
  Function: right(<string>, <number>)
 
  This function returns the last <number> characters from the right-hand
  side of <string>.
 
  Example:
    > say right(foobarbaz,4)
    You say "rbaz"
 
  See also: left(), mid()

& LPOS()
  Function: lpos(<string>, <character>)
 
  This function returns a list of the positions that <character> occupies
  in <string>, with the first character of the string being 0. (Note that
  this differs from the pos() function, but it consistent with functions
  such as mid().)
 
  If <character> is null, a space is assumed.
 
  Example:
    > say lpos(a-bc-def-g,-)
    You say "1 4 8"
 
& POS()
  pos(<string1>,<string2>)
 
  This function returns the position that string1 begins in string2,
  with the first position being 1.
  If string1 is not in string2, then it returns #-1.
 
  Example: pos(man,superman) returns 6
& MATCH()
  Function: match(<string>, <pattern>[, <delim>])
 
  This function matches <pattern> against each word of <string>, returning
  the number of the first word that matches.  If no words match then 0 is
  returned.  The case of the characters being matched is not significant.
 
  The pattern may contain the wildcards '*' and '?'.  '?' matches any one
  character, while '*' matches any number of characters, including none.
  So 's?x' would match 'sex' or 'six', but not to 'socx', but 's*x' would
  match any of them.

  <delim> may be used specified to specify a delimiter other than a space.

  Examples:
    > say match(This is a test, test)
    You say "4"
    > say match(This is a test, is)
    You say "2"
    > say match(This is a test, *is*)
    You say "1"
    > say match(This is a test, *not*)
    You say "0"
    > say match(This is a test, is a)
    You say "0"
  See also: LISTS, member(), matchall(), strmatch().

& MATCHALL()
  Function: matchall(<string>,<pattern>[,<delim>])
 
  This function works identically to the match() function, save that it
  returns all matches, not just the first: It returns the index numbers of
  all words in the list <string> which match <pattern>. If none match, an
  empty string is returned.
 
  Examples:
 
  > say matchall(This is a test of a test,test)
  You say "4 7"
  > say matchall(This is testing a test,tes*)
  You say "3 5"
 
  See also: LISTS, match(), strmatch(). 
& STRMATCH()
  Function: strmatch(<string>,<pattern>)
 
  This function matches <pattern> against the entire <string>, returning 1
  if it matches and 0 if it does not.  The case of the characters being
  matched is not significant.
 
  The pattern may contain the wildcards '*' and '?'.  '?' matches any one
  character, while '*' matches any number of characters, including none.
  So 's?x' would match 'sex' or 'six', but not to 'socx', but 's*x' would
  match any of them.
 
  Examples:
    > say strmatch(This is a test,*Test)
    You say "1"
    > say strmatch(This is a test,*This)
    You say "0"
    > say strmatch(This is a test,*is*is*)
    You say "1"
  See also: match(), member().

& ELEMENTS()
  elements(<list of words>,<list of numbers>[,<delim>])
 
  This function returns the words in <list of words> that are in the
  positions specified by <list of numbers>. Optionally, a list delimiter
  other than a space can be separated.
 
  Examples:
    > say elements(Foo Ack Beep Moo Zot,2 4)
    You say "Ack Moo"
    > say elements(Foof|Ack|Beep|Moo,3 1,|)
    You say "Beep|Foof"

& EXTRACT()
  extract(<string>, <first>, <length>[, <delim>])
 
  Extract returns a string of length words, starting with the first 
  word. Unlike letters, the first word in a string is number 1, 
  instead of 0.
 
  <delim> may be used to specify a delimiter other than a space.

  Examples:
    > say extract(This is a really neat example, 4, 2)
    You say "really neat"
    > say extract(Another@funky@test@for@extract, 3, 3)
    You say "test@for@extract" 
  See also: index(), insert(), ldelete(), replace().

& INDEX()
  Function: index(<list>,<character>,<first>,<length>)
  
  This function is similar to EXTRACT(), except that an item in the
  list may be more than one word; instead of a space being used to
  separate items in the list, <character> is used. The function returns 
  <length> items starting from that in the <first> position. Trailing
  spaces are trimmed. The comma cannot be used as the <character> separator. 
 
  Example:
    > say [index(Cup of Tea | Mug of Beer | Glass of Wine, |, 2, 1)]
    You say, "Mug of Beer"
  See also: extract().

& GRAB()
  Function:  grab(<list>, <pattern>[, <delim>])
  
  This function matches <pattern> against each word in <list>, returning
  the first word that matches. If no words match, then an empty string
  is returned. The match is not case-sensitive, and wildcard characters
  are permitted. <delim> may be used to specify a list delimiter other
  than a space.
 
  Examples:
    > say grab(This is a new test,?e*)
    You say "new"
    > say grab(Holodeck:#10~Airlock:#58~Dorm:#12~Brig:#83,Airlock:*,~)
    You say "Airlock:#58"
 
  See also: LISTS, match().
 
& FLAGS()
  flags(<object>)
 
  Flags returns a string consisting of the flags attached to the 
  object. The string is, however, just one word.  Note that @switch
  is case-INsensitive.  i.e. p=P as far as it is concerned.  I wish
  that P=NP....
& NUM()
  num(<object>)
 
  Returns the dbref number of the object, which must be in the same 
  room as the object executing num.
  See also: locate().
& CON()
  con(<object>)
 
  Con returns the first object in the list of objects carried by 
  thing. Just the first, and only the first.  See NEXT.
& LOC()
  Function: loc(<object>)
 
  Returns the number of the location where <object> is.  You must either
  control the object or be nearby for it to work.  When used on an exit it
  returns the destination of the exit.  You can also use loc() to find the
  location of players that are not set UNFINDABLE.
 
  Example:
    > look
    Mortal's Room(#367R)
    A bare room with nothing in it but a bed and a chair.
    Contents:
    hat(#368)
    > say loc(me)
    You say "#367"
    > enter hat
    hat(#368)
    Contents:
    cat(#325)
    > say loc(me)
    You say "#368"
    > say loc(here)
    You say "#367"
  See also: rloc(), room(), where().

& RLOC()
  Function: rloc(<object>,<levels>)
 
  This function may be used to get the location of an object's location
  (for which you would previously use 'loc(loc(<object>))', which fails if you
  don't control <object>'s location).  <levels> indicates the number of
  nested 'loc' calls to make, so 'loc(loc(<object>))' could be replaced with
  'rloc(<object>,2)'.  If rloc() encounters a room, the dbref of the room
  is returned.
 
  You must either control the object or be nearby for it to work.  When used
  on an exit it returns the destination of the exit.  You can also use rloc()
  to find the location of players that are not set UNFINDABLE.
 
  rloc(<object>,0) is the same as num(<object>), and rloc(<object>,1) is the
  same as loc(<object>).
 
  See also: loc(), where().

& WHERE()
  Function: where(<object>)
 
  This function returns the "true" location of an object. You must control
  the object or be near it in order for it to work. For players and things,
  the "true" location is the normal location of the object. For exits, the
  "true" location is the source room. For rooms, it is #-1.
  See also: loc(), rloc().

& OWNER()
  Function: owner(<object>)
            owner(<object>/<attrib>)
 
  The first form of the owner() function returns the dbref of the owner of the
  object.  The object must either be yours or nearby.
 
  The second form returns the owner of an attribute on the named object.
  You must own either the object or the attribute.

& NAME()
  name(<dbref>)
 
  This function returns the name of the indicated object.  When called with
  an exit it returns the only the first alias.

  See also: fullname().

& FULLNAME()
  Function: fullname(<dbref>)
  
  This function returns the full name of the indicated object.  This is the
  same as name() in all cases except when <dbref> is an exit, then all the
  aliases are returned as well.
 
  See also: name().

& NEXT()
  next(<thing>)
 
  If thing is an exit in a room, then next will return the next 
  nondark exit in the list of exits for that room.  If thing is an 
  object, then next will return the next object in the inventory list 
  that the object is in.  Otherwise, it returns a '#-1' string.
& AND()
  Function: and(<boolean1>,<boolean2>[,<booleanN>]...)
 
  Takes two or more booleans, and returns 1 if they are all each equivalent
  to true(1).
 
  This function stops evaluating cases as soon as something is false.
 
  See also: BOOLEAN VALUES, or(), not(), xor().
& OR()
  Function: or(<boolean1>,<boolean2>[,<booleanN>]...)
 
  Takes two or more booleans, and returns 1 if at least one is equivalent
  to true(1).
 
  This function stops evaluating cases as soon as something is true.
 
  See also: BOOLEAN VALUES, and(), not(), xor().
& NOT()
  Function: not(<boolean>)
 
  Takes a boolean value, and returns its inverse.  So, if the input is
  equivalent to true(1) it returns a 0, and if the input is equivalent to
  false(0), it returns a 1.
 
  See also: BOOLEAN VALUES, and(), or(), xor().
& XOR()
  Function: xor(<boolean1>,<boolean2>[,<booleanN>]...)
 
  Takes two or more booleans, and returns 1 if an odd number of them are
  equivalent to true(1).
 
  See also: BOOLEAN VALUES, and(), nor(), or().
& gt()
  Function: gt(<integer1>,<integer2>)
 
  Takes two integers, and returns 1 if and only if <integer1> is greater than
  <integer2>, and 0 otherwise.  Warning: passing anything but integers will
  produce unexpected results, as non-numeric strings usually are treated
  as numeric 0.
 
  Example:
    > say gt(4,5)
    You say "0"
    > say gt(5,5)
    You say "0"
    > say gt(6,5)
    You say "1"
    > say gt(foo, bar)
    You say "0"
  See also: lt(), lte(), gte(), eq(), neq(), comp().

& gte()
  Function: gte(<integer1>,<integer2>)
 
  Takes two integers, and returns 1 if and only if <integer1> is greater than
  or equal to <integer2>, and 0 otherwise.  Warning: passing anything but
  integers will produce unexpected results, as non-numeric strings usually are
  treated as numeric 0.
 
  Example:
    > say gte(4,5)
    You say "0"
    > say gte(5,5)
    You say "1"
    > say gte(6,5)

    You say "1"
  See also: lt(), lte(), gt(), eq(), neq(), comp().

& lt()
  Function: lt(<integer1>,<integer2>)
 
  Takes two integers, and returns 1 if and only if <integer1> is less than
  <integer2>, and 0 otherwise.  Warning: passing anything but integers will
  produce unexpected results, as non-numeric strings usually are treated
  as numeric 0.
 
  Example:
    > say lt(4,5)
    You say "1"
    > say lt(5,5)
    You say "0"
    > say lt(6,5)
    You say "0"
    > say lt(foo, bar)
    You say "0"
  See also: lte(), gte(), gt(), eq(), neq(), comp().

& lte()
  Function: lte(<integer1>,<integer2>)
 
  Takes two integers, and returns 1 if and only if <integer1> is less than or
  equal to <integer2>, and 0 otherwise.  Warning: passing anything but integers
  will produce unexpected results, as non-numeric strings usually are treated
  as numeric 0.
 
  Example:
    > say lte(4,5)
    You say "1"

    You say "1"
    > say lte(6,5)
    You say "0"
    > say lte(foo, bar)
    You say "1"
  See also: lt(), gte(), gt(), eq(), neq(), comp().

& eq()
  Function: eq(<integer1>,<integer2>)
 
  Takes two integers, and returns 1 if they are equal and 0 if they are not.
  Warning: passing anything but integers will produce unexpected results,
  as non-numeric strings usually are treated as numeric 0.
 
  Example:
    > say eq(1,-1)

    > say eq(5,5)
    You say "1"
    > say eq(foo, bar)
    You say "1"
  See also: lt(), lte(), gte(), gt(), neq(), comp().

& neq()
  Function: neq(<integer1>,<integer2>)
 
  Takes two integers, and returns 1 if they are not equal and 0 if they are
  equal.  Warning: passing anything but integers will produce unexpected
  results, as non-numeric strings usually are treated as numeric 0.
 
  Examples:
    > say neq(1,-1)
    You say "1"
    > say neq(5,5)
    You say "0"
    > say neq(foo, bar)
    You say "0"
  See also: lt(), lte(), gte(), gt(), eq(), not(), comp().

& cat()
  Function: cat(<string>[,<stringN>])
 
  cat returns a string made up of the contents of string1 through stringN,
  with each string separated from its neighbors by a space.
 
  Example:
    > say cat(this is, a test)
    You say "this is a test"
    > say cat(This is,another,test of the,CAT function)
    You say "This is another test of the CAT function"

& member()
  Function: member(<list>, <word>[, <delim>])
 
  Member takes a list and a word, and returns the position of that word
  within the list.  If the word does not occur in the list, then 0 is
  returned.  Unlike match(), member() does not check for wildcarding,
  and the cases of <list> and <word> are significant.  A word is defined as
  a string which has no interior spaces.  So 'hello' would be one word,
  while 'hello there' would be two.

  <delim> may be used to specify a delimiter other than a space.
 
  Example:
    > say member(This is a member test, member)
    You say "4"
    > say member(This is a member test, Member)
    You say "0"
    > say member(This is a member test, *e*)   
    You say "0"
    > say member(This is a member test, is a)
    You say "#-1 CAN ONLY TEST ONE ELEMENT"
 
  See also: LISTS, match(), strmatch().

& remove()
  Function: remove(<list>, <word>[, <delim>])
 
  Remove takes a list and a word, and returns the list, with the word deleted
  from it.  <delim> may be used to specify a delimiter other than a space.
 
  Example:
    > say remove(this is a test, is)
    You say "this a test"
    > say remove(You can't remove, this)
    You say "You can't remove"
    > say remove(You can't remove multiple words, You can't)
    You say "#-1 CAN ONLY DELETE ONE ELEMENT"
    > say remove(How about an o-separated list, w ab, o) 
    You say "Hout an o-separated list"

& STARTTIME()
  Function: starttime()
 
  Returns a string which is the time the MUSH last rebooted.  The time
  is in the same format as the TIME() function returns.
 
  Example:
    > say starttime()
    You say "Sat Dec  7 00:09:13 1991
  See also: convtime().

& SECS()
  Function: secs()
 
  Returns the number of elapsed seconds since midnight, January 1, 1970.
  This is an easy way to time things.
 
  Example:
     > say secs()
     You say "692636020"
     ... wait a bit ...
     > say secs()
     You say "692636043"
  See also: convsecs(), convtime(), time().

& WORDS()
  words(<string>[, <delim>])
 
  Returns the number of words in <string>.  <delim> may be used to specify
  a delimiter other than a space.
 
  Example:
    > say words(This is a test)
    You say "4"
    say words(Would you like coffee or perhaps tea?)
    > You say "7"
    say words(This:is:a:colon:separated:list,:)
    > You say "6"

& VERSION()
  Function: version()
 
  Returns a string which contains various version information for the MUSH
  you're on.
 
  Example:
     > version
     TinyMUSH Beta version 2.0 patchlevel 0 #3
     Build date: Thu Dec  5 10:10:07 EST 1991
     > say version()
     You say "TinyMUSH Beta version 2.0 patchlevel 0 #3"

& HOME()
  home(<object>)
 
  Returns the object's home.
 
  Example:
    > exam me
    Mortal(#226Pc)
    Type: PLAYER Flags: CONNECTED
    Desc:Just a plain, old boring Mortal. You know.
    Owner: Mortal  Key: VA:foobar Clams: 920
    Last:Thu Dec 19 08:57:21 1991
    Home: Mortal's Room(#367R)
    Location: The Town Square
    > say home(me)
    You say "#367"

& MONEY()
  Function: money(<object>)
 
  Returns an integer equal to the amount of money <object> has (if it is a
  player) or is worth (otherwise).
  Example:
    > score
    You have 1052 clams.
    > say money(me)
    You say "1052"
    > exam sac test
    Sac Test(#287V)
    Type: THING Flags: VISUAL
    Owner: Beaker  Key: *UNLOCKED* Clams: 20
    Home: Limbo(#0RLDAJ)
    Location: The Town Square
    > say money(sac test)
    You say "20"

& XCON()
  Function: xcon(<object>, <element number>, <number of objects>)
 
  Returns a space-separated list of contents of <object>, starting from
  the <element number>'d object contained, up to <number of objects>. 
  This is useful for contents lists where a normal lcon() call would 
  exceed the maximum buffer length for function output.
 
  Example:
    > i
    t1(#366)
    t2(#411)
    t3(#700)
    t4(#108)
    radio(#223)
    The Wizard's Pointy Hat(#188SO)
    You have 42463 clams.
    > say xcon(me,3,3)
    You say "#700 #108 #223"
 
& LCON()
  Function: lcon(<object>)
 
  Returns a space-separated list of the contents of <object>.
 
  Example:
    > i
    t1(#366)
    radio(#223)
    The Wizard's Pointy Hat(#188SO)
    You have 42463 clams.
    > say lcon(me)
    You say "#366 #223 #188"
  See also: lexits(), @dolist.

& LEXITS()
  Function: lexits(<loc>)
 
  Returns a space-separated list of the exits in <loc> and its parents.
  Dark exits are not returned unless you own the location.
 
  Example:
    > look here
    The Town Square
    You are in the town square.  All around you .....
    Obvious exits:
    foo  up  southeast  sw  north  
    > say lexits(here)
    You say "#302 #10 #9 #8 #6"
  See also: lcon(), @dolist, PARENT OBJECTS.

& SECURE()
  Function: secure(<string>)
 
  Returns <string> after replacing the characters [](){};,%\$ with spaces.
  This prevents strings entered by players from causing undesired side
  effects when used, such as making your object perform unintended commands
  or give out information to which you have access.  Note that this function
  is only needed when the resulting string is to be passed through the @force
  command or be used as an attribute for an object (like the success message
  for a mail message object).
 
    > @va me=Sneak a peek at Wiz's desc... [get(#1/desc)]
    > say secure(%va)
    You say "Sneak a peek at Wiz's desc...  get #1/desc  "
    > say secure($foobar:this {is} a really, tough ; test.)
    You say " foobar:this is a really tough   test."
 
  Note: 'say secure(Sneak a peek at Wiz's desc... [get(#1/desc)])' does not
  produce the expected result because the argument is evaluated BEFORE being
  processed by secure(), therefore the [get()] call has already been
  performed.
  See also: escape().

& ESCAPE()
  Function: escape(<string>)
 
  Returns <string> after adding an escape character (\) at the start of the
  string and also before each of the characters %;[]{}\ that appear in the
  string.  This prevents strings entered by players from causing undesired
  side effects when used, such as making your object perform unintended
  commands or give out information to which you have access.  Note that this
  function is only needed when the resulting string is to be passed through
  the @force command or be used as an attribute for an object (like the
  success message for a mail message object).  This function has the 
  advantage over the secure() function in that the string the user sees
  after evaluating it is the same as the original string.
 
  Example:
    You say "\Sneak a peek at Wiz's desc... \[get(#1/desc)\]"
 
  Note: 'say escape(Sneak a peek at Wiz's desc... [get(#1/desc)])' does not
  produce the expected result because the argument is evaluated BEFORE being
  processed by escape(), therefore the [get()] call has already been
  performed.
  See also: secure().

& MUDNAME()
  Function: mudname()
 
  Returns the name of the MUD.  This is usually (but not necessarily) the name
  that appears in the various mud lists, and is the name that the mud is
  listed under in reports from RWHO servers (that is, if the mud sends its
  WHO information to an RWHO server).
 
  Example:
    > say mudname()
    You say "TestMUSH"

& CAPSTR()
  Function: capstr(<string>)
 
  Returns <string> with the first character capitalized.  If the first
  character is not a letter, this function returns the string unmodified.
 
  Example:
    > say capstr(this is a string I want capitalized)
    You say "This is a string I want capitalized"
  See also: lcstr(), ucstr().

& LCSTR()
  Function: lcstr(<string>)
 
  Returns <string> with all letters converted to lowercase.
 
  Example:
    > say lcstr(This is something I want to TEST)
    You say "this is something i want to test"
  See also: capstr(), ucstr().

& UCSTR()
  Function: ucstr(<string>)
 
  Returns <string> with all letters converted to uppercase.
 
  Example:
    > say ucstr(This is a test, really!)
    You say "THIS IS A TEST, REALLY!"
  See also: capstr(), lcstr().

& LNUM()
  Function:  lnum(<number>[,<other>][,<sep>])
 
  If only given one argument, this function returns a list of numbers from
  0 to <number>-1.  <number> must be at least 1.
 
  If given at least two arguments, this function returns a list of numbers
  from <number> to <other>. If <other> is less than <number>, the list
  will return in descending order. Negative integers are permissible.
  <sep> is used as the separator character, if given.
 
  Examples:
    > say lnum(5) 
    You say "0 1 2 3 4"
    > say lnum(3,7)
    You say "3 4 5 6 7"
    > say lnum(4,-2)
    You say "4 3 2 1 0 -1 -2"
    > say lnum(2,6,|)
    You say "2|3|4|5|6"

& LATTR()
  Function: lattr(<object>[/<wild-pattern>])
 
  Returns a list of the attributes set on <object>.  If <wild-pattern> is
  given, only attributes matching it are returned.
 
  Example:
    > exam me
    Mortal(#226Pc)
    ....
    VC:Mon Sep  9 12:09:01 1991
    VE:baz
    Last:Thu Dec 19 08:57:21 1991
    VV(#2+):Foof!
    Domain:Abusees
    ....
    > say lattr(me)
    You say "Desc VC VE Last VV Domain"
    > say lattr(me/v*)
    You say "VC VE VV"
 
  See also: @dolist.

& REVERSE()
  Function: reverse(<string>)
 
  Reverses the order of the characters of <string>.
 
  Examples:
    > say reverse(This is a test)
    You say "tset a si sihT"
    > say reverse(This is a test, Really...)
    You say "...yllaeR ,tset a si sihT"
    > say reverse(A man, a plan, a canal -- Panama!)
    You say "!amanaP -- lanac a ,nalp a ,nam A"
  See also: revwords().

& REVWORDS()
  Function: revwords(<string>[, <delim>])
 
  Reverses the order of the words of <string>.  A word is considered to be
  any sequence of nonblank characters, separated by blanks, so punctuation
  characters that follow a word are considered part of the word.

  <delim> may be used to specify a delimiter other than a space.
 
  Examples:
    > say revwords(This is a test, Really...)
    You say "Really... test, a is This"
    > say revwords(Was it a cat I saw?)
    You say "saw? I cat a it Was"
  See also: reverse().

& BEFORE()
  Function: before(<string1>, <string2>)
 
  Returns the portion of <string1> that occurs before <string2>.  If <string2>
  does not occur in <string1>, the entire string is returned.
  If you want to return the portion of the string after the first space,
  use the first() function instead.
 
  Examples:
    > say before(This is a test,a)
    You say "This is "
    > say before(This is a test,is)
    You say "Th"
    > say before(This is a test, nope) 
    You say "This is a test"
  See also: after(), first(), rest().

& AFTER()
  Function: after(<string1>, <string2>)
 
  Returns the portion of <string1> that occurs after <string2>.  If <string2>
  does not occur in <string1>, a null string is returned.
  If you want to return the portion of the string after the first space,
  use the rest() function instead.
 
  Examples:
    > say after(This is a test,a)
    You say " test"
    > say after(This is a test,is)
    You say " is a test"
    > say after(This is a test, nope)
    You say ""
  See also: before(), first(), rest().

& ROOM()
  Function: room(obj)
 
  Returns the number of the room that <obj> is in, or would be in if it
  executed LEAVE commands until it got to a room.  You can find out the
  containing room of objects you own, nearby objects, and findable players.
 
  Example:
    > i
    You are carrying:
    hat(#368)
    cat(#325)
    > look
    Mortal's Room(#367R)
    A bare room with nothing in it but a bed and a chair.
    > say I am in [room(me)], the cat is in room [room(cat)].
    You say "I am in #367, the cat is in room #367."
    > @fo hat=get cat 
    cat has left.
    > say The cat is in [loc(#325)] within room [room(#325)].
    You say "The cat is in #368 within room #367."
  See also: loc(), UNFINDABLE.

& SEARCH()
  Function: search([<player>] [<class>=<restriction>[,<low>[,<high>]]])
 
  The search() function returns a list of objects that match the search
  criteria, which are the same as with the @search command.  This function
  costs as much as the @search command, so repeated use is expensive.
 
  Caution: if you use the [ and ] characters in an Eval selection you will
  need to escape them.
 
  Examples:
    > say search()
    You say "#226 #289 #325 #364 #368 #369"
    > @stats me
    6 objects = 0 rooms, 0 exits, 5 things, 1 players. (0 garbage)
    > say search(eval=\[eq(money(##),1)\])
    You say "#289 #325 #364 #368 #369"
    > say search(player=wizard)
    You say "#1"
  See also: @search, SEARCH CLASSES.

& STATS()
  Function: stats([<player>])
 
  This function returns information about the number of objects on the MUSH,
  much like the @stats command.  If the argument is omitted or is 'all', then
  the stats for the entire MUSH are returned, otherwise the stats for the
  named player are returned.  You can only get stats for yourself.
 
  The stats are returned as a set of 6 numbers, in the same order as reported
  by the @stats command: total objects, rooms, exits, things, players, and
  garbage.  This command costs as much as the equivalent @stats command (ie:
  '@stats/all' or '@stats <player>', not the free '@stats').
 
  Examples:
    > @stats me
    6 objects = 0 rooms, 0 exits, 5 things, 1 players. (0 garbage)
    > say stats(me)
    You say "6 0 0 5 1 0"
    > say stats()
    You say "377 51 165 134 20 7"
    > @stats/all
    377 objects = 51 rooms, 165 exits, 134 things, 20 players. (7 garbage)
  See also: @stats.

& ITER()
  Function: iter(<list>, <eval>[, <delim>])
 
  <list> is a <delimiter>-separated list of strings, which can be object
  numbers, attributes, or arbitrary words.  <eval> is a string that is to be
  evaluated once for each item in <list>, replacing the special symbol ## with
  the corresponding item from <list>.  A space-separated list of the results
  of these evaluations is returned to the caller.  The effect is very similar
  to @dolist, except that the results are made into a list and returned, not
  executed.
 
  Examples:
    > say iter(This is a test,strlen(##))
    You say "4 2 1 4"
    > say iter(This is a test,{strlen(##)})
    You say "4 2 1 4"
    > say iter(lnum(10),mul(mul(##,##),10))
    You say "0 10 40 90 160 250 360 490 640 810"
    > say iter(lcon(me),[name(##)]..[money(##)])
    You say "test..1 t1..1 radio..1 The Wizard's Pointy Hat..1"
    > say iter(Was it a cat I saw,words(##),s)
    You say "1 4 1"
  See also: @dolist, parse().

& LOCATE()
  Function: locate(<looker>,<string>,<where>)
 
  The locate function is used to look for an object from the perspective of
  <looker> (You must own <looker>).  The database number of the item that
  is found is returned.  The <where> parameter specifies a list of places to
  look, from this list:
    a    - Look for absolute references (#<number>)
    c    - Look for exits carried by <looker> (and by <looker>'s parents).
    e    - Look for exits in <looker>'s location (and the location's parents).
    h    - Look for 'here', which matches <looker>'s location.
    i    - Look in <looker>'s inventory.
    m    - Look for 'me', which matches <looker>.
    n    - Look for <looker>'s neighbors (other objects in the same location).
    p    - Look for player names prefixed by a '*'
    *    - Look for everything in the above list.
{ 'help locate2' for more }
& locate2
  You may also specify qualifiers in <where> to help resolve possible
  ambiguities:
    E    - Prefer exits over other types.
    L    - Prefer unlocked exits over locked exits.
    P    - Prefer players over other types.
    R    - Prefer rooms over other types.
    T    - Prefer things over other types.
    V    - Report "Can't find..." and "Which one..." errors to <looker>.
    X    - Select randomly if search finds multiple ("ambiguous") matches.
 
  If nothing matches, the value #-1 is returned.  If more than one thing
  matches, but nothing matches exactly, the value #-2 is returned.  If more
  than one thing exactly matches, one is chosen at random.  If you specify
  more than one type preference (E, P, R, or T), then the last one entered
  is the one that is obeyed.  The default is for no type to be preferred.

  Examples:
    > i
    test1(#378)
    test(#376)
    You have 42463 clams.
    > look
    Nullspace(#250R)
    test1(#382)
    > say locate(me,test,i)
    You say "#376"
    > say locate(me,test,n)
    You say "#382"
    > say locate(me,test1,in)
    You say "#378"
    > say locate(me,test1,in)
    You say "#382"
    > say locate(me,tes,in)
    You say "#-2"
    > say locate(here,tes,*)
    You say "#382"
    > say locate(me,out,e)
    You say "#252"
    > say locate(me,here,*)
    You say "#250"
 
  See also: num(), PARENT OBJECTS.

& EDIT()
  Function: edit(<string>,<from>,<to>)
 
  This function edits <string>, replacing all occurrences of the substring
  <from> with the string <to>.  If <from> is '$', then <to> is appended to
  <string>, while if <from> is '^', then it is prepended.
 
  Examples:
    > say edit(This is a test,is,x)   
    You say "Thx x a test"
    > say edit(Atlantic,^,Trans)
    You say "TransAtlantic"
  See also: @edit.

& OBJEVAL()
  Function:  objeval(<object>,<expression>)
 
  This function allows you to evaluate <expression> from the viewpoint of
  <object>. You must own <object>, or have Wizard powers. If you do not,
  the function defaults to evaluating from your viewpoint.
  
  This function is useful for securing privileged objects which need
  to evaluate attributes on things owned by other, or otherwise restrict
  access to privileged information. For example, it's useful for a global
  '+who' object to call the LWHO() function from the viewpoint of the
  enactor (i.e, a 'objeval(%#,lwho())' call), so that if the player is
  mortal, DARK wizards are hidden, but if the player is a wizard, DARK
  wizards appear on the list.
 
& U()
  Function: u([<obj>/]<attr>[,<arg>]...)
 
  The u function evaluates an attribute, either from the object performing the
  function or from another object you own, passing in arguments and returning
  the result.

  When evaluating the fetched attribute, %# refers to the original enactor and
  not the 'calling' object, and 'me' refers to the object that supplied the
  attribute.
 
  Examples:
    > @va me=Word is [extract(v(vb),add(%0,1),1)], arg2 is %1.
    > @vb me=This is a test of the u function.
    > say u(va,4,Testing 123)
    You say "Word is of, arg2 is Testing 123."
    > say u(va,7)
    You say "Word is function., arg2 is ."
    > say u(me/va,6,Foobar)
    You say "Word is u, arg2 is Foobar."
  See also: s(), v(), get(), get_eval(), map().

& ULOCAL()
  Function:  ulocal([<obj>/]<attr>[,<arg>]...)
 
  The ulocal() function is almost identical to u() in function:  it
  evaluates an attribute, either from the object performing the function,
  or another object that you control or has the same owner as you, passing
  in arguments and returning the result. When evaluating the fetched
  attribute, %# refers to the original enactor and not the 'calling' object;
  'me' refers to the object that supplied the attribute.
 
  However, unlike the u() function, the global registers r(0) through r(9)
  (%q0 - %q9) are preserved in their initial state. This means that functions
  "below" the level of the u() can reset global registers for temporary
  calculations, without needing to worry about "clobbering" the original
  values.
 
  This makes ulocal() particularly useful for global or shared code which
  calls arbitrary u() functions, where global register values need to be
  preserved from accidental user clobbering.
 
  See "help ulocal2" for examples.
 
& ULOCAL2
  Example of ulocal():
    > &FRUIT me=apples bananas oranges pears
    > &SUB-FUNCTION me=[setq(0,v(FRUIT))][extract(%q0,match(%q0,%0),1)]
    > &TOP-FUNCTION me=[setq(0,are delicious!)][ulocal(SUB-FUNCTION,%0)] %q0
    > say u(TOP-FUNCTION,b*)
    You say "bananas are delicious!"
 
  If SUB-FUNCTION had been called with u() instead of ulocal():
    > &TOP-FUNCTION me=[setq(0,are delicious!)][u(SUB-FUNCTION,%0)] %q0
    > say u(TOP-FUNCTION,b*)
    You say "bananas apples bananas oranges pears"
 
  In this second example, in SUB-FUNCTION, %q0 was set to "apples bananas
  oranges pears", so that when the u() "returned" and TOP-FUNCTION evaluated
  %q0, this is what was printed. In the first example, ulocal() reset the
  value of %q0 to its original "are delicious!"
 
  See also:  u(), setq(), r()
& SWITCH()
  Function: switch(<str>[,<pat1>,<res1>]...[,<dflt>])
 
  The switch function compares <str> against <pat1>, <pat2>, etc (allowing *
  to match any number of characters and ? to match any 1 character), and
  returns the corresponding <resN> parameter for the first <patN> pattern
  that matches.  If none match, then the default result <dflt> is returned.
 
  Example:
    > say switch(c,*a*,A,*b*,B,*c*,C,*d*,D,E)
    You say "C"
    > say switch(f,*a*,A,*b*,B,*c*,C,*d*,D,E)
    You say "E"
    > say switch(cab,*a*,A,*b*,B,*c*,C,*d*,D,E)
    You say "A"
    > say switch(f,*a*,A,*b*,B,*c*,C,*d*,D)  
    You say ""
  See also: @switch, match().

& SPACE()
  Function: space(<count>)
 
  Returns the number of indicated spaces.  If <count> is missing, negative,
  or cannot be converted to a number, one space is returned.  This function
  is useful when you want to pass a single space (or more than one) as a
  function to an argument, because normally leading and trailing spaces are
  stripped from function arguments.
 
  Examples:
    > say space(4)
    You say "    "
    > say edit(Foo bar bletch, space(), X)
    You say "FooXbarXbletch"

& PARENT()
  Function: parent(<obj>)
 
  Returns the parent of <obj>.  Returns #-1 if <obj> cannot be found or
  if you do not own <obj> and it is not set VISUAL.
 
  Example:
    > say parent(me)
    You say "#-1"
    > say My va is [v(va)].
    You say "My va is "
    > @parent me=test
    Parent set.
    > say parent(me)
    You say "#323"
    > say My va is [v(va)].
    You say "My va is Testing 123"
  See also: @parent, PARENT OBJECTS.

& SIGN()
  Function: sign(<number>)
 
  Returns -1, 0, or 1 depending on whether its argument is negative, zero, or
  positive (respectively).
 
  Example:
  > say sign(-4)
  You say "-1"
  > say sign(4)
  You say "1"
  > say sign(0)
  You say "0"
  > say sign(-1)
  You say "-1"

& CONN()
  Function: conn(<player>)
 
  Returns the number of seconds that <player> has been connected.  If <player>
  is not connected then -1 is returned.  If <player> is connected more than
  once, the longest connect time is returned.
 
  Example:
    > WHO
    Player Name          On For Idle  Doing
    Wizard                00:04   1m

    You say "-1"
  See also: WHO, idle(), lwho().

& IDLE()
  Function: idle(<player>)
 
  Returns the number of seconds that <player> has been idle.  If <player>
  is not connected then -1 is returned.  If <player> is connected more than
  once, the smallest idle time is returned.
 
  Example:
    > WHO
    Player Name          On For Idle  Doing
    Wizard                00:04   1m
    Mortal                00:11   0s  
    Evinar                00:12   6m  
    Wizard                00:32   6s  
    3 Players logged in.
    > say idle(wiz)
    You say "6"
    > say idle(e)

  seconds the number is after Jan 1, 1970.
 
  Example:
    > say secs()
    You say "709395750"
    > say convsecs(709395750)
    You say "Wed Jun 24 10:22:54 1992"
  This function may also be called as secs2time().
  See also: convtime(), secs(), time().

& CONVTIME()
  Function: convtime(<time string>)
 
  This functions converts a time string to the number of seconds since
  Jan 1, 1970. A time string is of the format: Ddd MMM DD HH:MM:SS YYYY
  where Ddd is the day of the week, MMM is the month, DD is the day
  of the month, HH is the hour in 24-hour time, MM is the minutes,
  SS is the seconds, and YYYY is the year.
  If you supply an incorrectly formatted string, it will return -1.
 
  Example:
    > say time()
    You say "Wed Jun 24 10:22:54 1992"
    > say convtime(Wed Jun 24 10:22:54 1992)

& SCRAMBLE()
  Function:  scramble(<string>)
 
  This function scrambles a string, returning a random permutation of its
  characters. Note that this function does not pay any attention to spaces
  or other special characters; it will scramble these characters just like
  normal characters.
 
  Example:
    > say scramble(abcdef)
    You say "cfaedb"
 
  See also:  SHUFFLE()

& SORT()
  Function: sort(<list>[, <sort type>[, <delim>]])
 
  Takes a list of words, numbers, or dbref, and sorts them into ascending
  order.  Lexicographic order is used for words, and numeric order is used
  for numbers and dbrefs.
 
  <sort type> may be used to specify the type of sort to perform (use d for
  dbref, n for integer numeric, f for floating numeric, and a for
  alphanumeric).  If omitted or left blank, the sort() function will
  automatically determine the type of sort to perform.
 
  If <delim> is specified, it (rather than a space) is used to separate items
  in the list.  You may specify an alternate delimiter without specifying
  a sort type by passing a null <sort type> parameter.
 
  Examples:
    > say sort(This is a test)
    You say "This a is test"
    > say sort(98 99 100 101)
    You say "98 99 100 102"

  <list1> that aren't in <list2>. The list that is returned is sorted.
 
  If <delim> is specified, it (rather than a space) is used to separate items
  in the list.
 
  Example:
    > say setdiff(foo baz gleep bar, bar moof gleep)
    You say, "baz foo"
  See also: setinter(), setunion(), sort().

& SETINTER()
  Function: setinter(<list1>, <list2>[, <delim>])
 
  This function returns the intersection of two sets -- i.e., the elements
  that are in both <list1> and <list2>. The list that is returned is sorted.

  If <delim> is specified, it (rather than a space) is used to separate items
  in the list.
 
  Example:
    > say setinter(foo baz gleep bar, bar moof gleep)
    You say, "bar gleep"
  See also: setdiff(), setunion(), sort().

& SETUNION()
  Function: setunion(<list1>, <list2>[, <delim>])
 
  This function returns the union of two sets -- i.e., all the elements of
  both <list1> and <list2>, minus any duplicate elements. Think of it as
  CAT() without duplicated words.  The list returned is sorted.
 
  If <delim> is specified, it (rather than a space) is used to separate items
  in the list.
 
  Example:
    > say setunion(foo baz gleep bar, bar moof gleep)
    You say, "bar baz foo gleep moof"
  See also: setdiff(), setinter(), sort().

& MERGE()
  Function: merge(<string1>,<string2>,<character>)
  
  This function merges <string1> and <string2>, depending on <character>.
  If a character in <string1> is the same as <character>, it is replaced
  by the character in the corresponding position in <string2>.  The two
  strings must be of the same length.
  
  Spaces need to be treated specially. A null character is considered to
  equal a space, for <character>.
  
  Examples:
    > say merge(AB--EF,abcdef,-)
    You say, "ABcdEF"
    > say merge(AB[space(2)]EF,abcdef,)
    You say, "ABcdEF"
  See also: splice().

& REPEAT()
  Function: repeat(<string>,<number>)
  
  This function simply repeats <string>, <number> times.  No spaces are
  inserted between each repetition.
  
  Example:

    You say, "TestTestTestTestTest"

& SPLICE()
  Function: splice(<list1>, <list2>, <word>[, <delim>])
  
  This function splices <list1> and <list2> together. <list1> and <list2>
  are space-separated lists of words
  
  If a word in <list1> is the same as <word>, it is replaced by the word
  in the corresponding position in <list2>.  Both lists must have the
  same number of words.

  <delim> may be used to specify a delimiter other than a space.  
 
  Example:
    > say splice(foo bar baz,eek moof gleep,bar)
    You say, "foo moof baz"
  See also: merge().

& PI()

& map()
  Function: map([<obj>/]<attr>, <list>[, <delim>])
  
  This function is nearly identical to an iter() operating on u() function.

  the result of one step into the next step as %0, passing in the next element
  from the list as %1.

  If a base case is provided, it is used as the initial %0.  If not, the first
  list element is passed as %0 and the second is passed as %1, and subsequent
  iterations proceed normally.
  
  <delimiter> may be used to specify a delimiter other than space, but you
  must specify a base case in order to specify the delimiter.
 
  Examples:
    > &REP_NUM object=[%0][repeat(%1,%1)]
    > say fold(object/rep_num,1 2 3 4 5,->)
    You say "->122333444455555"
    > &ADD_NUMS object=add(%0,%1)
    > say fold(object/add_nums,1 2 3 4 5)
    You say "15"

& RJUST()
  Function: rjust(<string>, <length>[, <fill>])
 
  This function pads a string with leading <fill> characters, or with spaces
  if no fill character is given) ("right-justifies") so it is <length> long.
  If <string> is longer than <length>, the <string> is returned; it is not
  truncated.
 
  Examples:
    > say -[rjust(foo,6)]-
    You say "-   foo-"
    > say %r0[rjust(foo,6)]7%r01234567
    You say "
    0   foo7
    01234567"
    > say =[rjust(bar,5,.)]=
    You say "=..bar="
  See also: ljust(), strlen().

& LJUST()
  Functions: ljust(<string>, <length>[, <fill>])
 
  This function pads a string with trailing <fill> characters, or with spaces
  if no fill character is given) ("left-justifies") so it is <length> long.
  If <string> is longer than <length>, the <string> is returned; it is not
  truncated.
 
  Examples:
    > say -[ljust(foo,6)]-
    You say "-foo   -"
    > say %r0[ljust(foo,6)]7%r01234567
    You say "
    0foo   7
    01234567"
    > say =[ljust(bar,5,.)]=
    You say "=bar..="
  See also: rjust(), strlen().

& R()
  Function: r(<number>)
 
  The r() function is used to access "local registers", and returns
  the contents of the specified register. There are ten such registers,
  numbered 0 through 9.  The local registers are normally cleared at the
  start of each command, but are preserved across the commands that compose
  an actionlist, as well as commands that directly trigger actionlists, such
  as @switch, @trigger, and @dolist.
 
  This is equivalent to the substitution %q<number>; i.e., "r(0)" == "%q0".
 
  See also: setq().

& SETQ()
  Function: setq(<number>,<string>)
 
  The setq() function is used to copy strings into local registers.
  It returns a null string; it is a purely "side effect" function.

  There are ten local registers, numbered 0 through 9. They are cleared
  at the start of each command. They are most useful for storing complex
  function evaluations which are used repeatedly within a single command.
  The local registers may be read via the r() function or the %q substitution,
  and a common use of setq()/r() is to temporarily store the result of a
  complex evaluation whose result is needed more than once.
 
  setq() can be used to improve the readability of MUSH code, as well as to
  cut down the amount of time needed to do complex evaluations.
 
  Example:
    > &TEST me=Test on [mudname()] at [time()].
    > say [setq(0,u(TEST))]'[r(0)]' has length [strlen(r(0))].
    You say "'Test on TestMUSH at Tue Feb 23 17:00:51 1993.' has length 45."
  See also: r().

& SQUISH()
  Function:  squish(<string>[,<character>])
 
  This function will trim multiple occurrences of <character> (or a space, if 
  <character> is not specified) down to a single occurrence of <character>.
  This is useful for getting rid of big internal spaces, and the like.
 
  Examples:
    > @force me=@va me=Test\[space(5)\]Test   (which becomes 'Test     Test')
    > say squish(%va)
    You say "Test Test"
    > say squish(---ack-----oof---,-)
    You say "-ack-oof-"
 
  See also:  trim()

& TRIM()
  Function: trim(<string> [,<trim style> [,<trim character>]])
 
  This function will trim trailing and/or lead characters on the string
  that you specify.  <trim character> specifies the character to trim (default
  is space), and <trim style> tells the kind of trimming to perform (default
  is trim both sides of the string).
 
  The following values for <trim style> are recognized:
      'b' :   Trim both ends of the string (default)
      'l' :   Trim the left end of the string.
      'r' :   Trim the right end of the string.
  Note: anything else specified for <trim style> will trim both sides.
 
  Example:
    > say trim(;;;Wacka;;;,b,;)
    You say "Wacka"
    > say trim(%b%b%b Polly Parrot %b%b%b%b,,r)
    You say "    Polly Parrot"
    > say trim(---Trim Rules!---,l,-)
    You say "Trim Rules!---"
  See also: center(), ljust(), rjust().

& CENTER()
  Function: center(<string>,<width>[,<fill>])
 
  This function will center a string in a string <width> characters wide,
  using <fil> characters for padding on either end of the string for
  centering.  If no fill character is specified then a space is used.
  If <string> is longer than <width> characters, the string is returned
  unmodified.
 
  Example:
    > say center(a,5,-)
    You say "--a--"
    > say center(*BAMF*,15)
    You say "    *BAMF*     "

& INSERT()
  Function: insert(<list>, <pos>, <word>[, <sep>])
 
  This function inserts a word into <list> so that the word becomes the
  <pos>'th element of the list, and all subsequent list elements are moved
  down.  This means that it appears between the <pos-1>'th and <pos>'th
  elements of the original list.  This function may not be used to append
  a word to a list.
 
  <delim> may be used to specify a delimiter other than a space.
 
  Examples:
    > say insert(This is a test, 4, new)
    You say "This is a new test"
    > say insert(Yet@Another@List, 3, Funky, @)
    You say "Yet@Another@Funky@List"
  See also: extract(), ldelete(), replace().

& REPLACE()
  Function: replace(<list>, <pos>, <word>[, <sep>])
 
  This function inserts a word into <list> so that the word becomes the
  <pos>'th element of the list, and the word previously in that position
  is removed.  This means that it appears between the <pos-1>'th and
  <pos+1>'th elements of the original list, replacing the word at that
  position.  This function may not be used to append a word to a list.
 
  <delim> may be used to specify a delimiter other than a space.
 
  Examples:
    > say replace(This is a test, 4, quiz)
    You say "This is a quiz"
    > say replace(Yet@Another@Mundane@List, 3, Funky, @)
    You say "Yet@Another@Funky@List"
  See also: extract(), insert(), ldelete().

& LDELETE()
  Function: ldelete(<list>, <pos>[, <sep>])
 
  This function removes a word from <list> by position.
  <delim> may be used to specify a delimiter other than a space.
 
  Examples:
    > say ldelete(This is not a test, 3)
    You say "This is a test"
    > say ldelete(Yet@Another@Mundane@List, 3, @)
    You say "Yet@Another@List"
  See also: extract(), insert(), replace().

& ISDBREF()
  Function: isdbref(<string>)
 
  This function will return 1 if the string passed to it is a valid dbref.
  To be a valid dbref the string must begin with '#' and be followed by an
  integer.  Also, the dbref must exist in the current database as a valid
  object.  If the object fails either of these criteria, then a 0 is
  returned.
 
  Example:
     > say isdbref(#-1)
     You say "0"
     > say isdbref(#1)
     You say "1"
     > say isdbref(This is not a dbref)
     You say "0"

& ISNUM()
  Function: isnum(<string>)
 
  This function will return 1 if the argument is a valid number and 0
  if it is not.
 
  Example:
     > say isnum(22223.0000)
     You say "1"
     > say isnum(77)
     You say "1"
     > say isnum(22 L)
     You say "0"
     >say isnum(Bad Numbers!)
     You say "0"

& ISWORD()
  Function: isword(<string>)
 
  This function will return 1 if every character in <string> is a letter,
  and 0 if this is not true.
 
  Example:
     > say isword(Test)
     You say "1"
     > say isword(Test123)
     You say "0"

& FOREACH()
  foreach([<object>/]<attribute>,<string>)
 
  Maps a function onto a string.
 
  Each character in <string> has the user-defined function of the first
  argument performed on it; the character is passed to the function as
  %0. The results are concatenated.
 
  Example:
 
    > &add_one me=[add(%0,1)]
    > say [foreach(add_one, 54321)]
    You say "65432"
  
& MIX()
 
  mix([<object>/]<attribute>,<list 1>,<list 2>[,<delim>])
 
  This function is similar to MAP(), except that it takes the elements
  of both lists, one by one, and passes them to the user-defined function
  as %0 and %1, respectively, for elements of <list 1> and <list 2>.
  <delim> is used to separate elements; if it is not specified, it
  defaults to a space. The lists must have the same number of elements.
  
  Examples:
 
  > &add_nums me=[add(%0,%1)]
 
  > say [mix(add_nums,1 2 3 4 5,2 4 6 8 10)]
  You say "3 6 9 12 15"
 
  > say [mix(add_nums,1:3:5:7,0:2:4:6,:)]
  You say "1:5:9:13"

& PORTS()
  ports(<player name>)
 
  This function returns the list of descriptors ("ports") that a player,
  specified by full player name, or by dbref, is connected to. Only Wizards
  may use this function; if a user lacks the privileges, or the player is
  not connected, an empty list is returned. Otherwise, a list of ports is
  returned in order of most recent connection to least recent connection.
  These ports correspond to those given by the SESSION command.
  
& HASATTR()
  hasattr(<object>,<attribute>)

  Returns '1' if <object> has named <attribute> (and the attribute can be
  seen by the invoker), or 0 if not. If the specified object is invalid,
  "#-1 NO MATCH" will be returned.
 
& SORTBY()
  sortby([<obj>/]<attrib>,<list>[,<delimiter>])
 
  This sorts an arbitrary list according to the u-function <obj>/<attrib>.
  This u-function should compare two arbitrary elements, %0 and %1, and
  return zero (equal), a negative integer (element 1 is less than element 2)
  or a positive integer (element 1 is greater than element 2).
 
  A simple example, which imitates a normal alphabetic sort:
    > &ALPHASORT test=[comp(%0,%1)]
    > say [sortby(test/ALPHASORT,foo bar baz)]
    You say "bar baz foo"
 
  A slightly more complicated sort. #1 is "God", #2 is "Amby", "#3" is "Bob":
    > &NAMESORT me=[comp(name(%0),name(%1))]
    > say [sortby(NAMESORT,#1 #2 #3)]
    You say "#2 #3 #1"
 
  Warning: the function invocation limit applies to this function. If
  this limit is exceeded, the function will fail _silently_. List and
  function sizes should be kept reasonable.
 
& MUNGE()
  munge([<object>/]<attribute>,<list 1>,<list 2>[,<delimiter>])
  
  This function takes two lists of equal length. It passes the entirety of
  <list 1> to the user-defined function as %0. Then, this resulting list
  is matched with elements in <list 2>, and the rearranged <list 2> is
  returned. This is useful for doing things like sorting a list, and then
  returning the corresponding elements in the other list. If a resulting
  element from the user-defined function doesn't match an element in the
  original <list 1>, a corresponding element from <list 2> does not appear
  in the final result.
 
  For example: Consider attribute PLACES, which contains "Fort Benden Ista",
  and another attribute DBREFS, which contains the dbrefs of the main JUMP_OK
  location of these areas, "#20 #9000 #5000". We want to return a list of
  dbrefs, corresponding to the names of the places sorted alphabetically. The
  places sorted this way wouuld be "Benden Fort Ista", so we want the final
  list to be "#9000 #20 #5000". The functions, using munge(), are simple:
 
  > &sort_alpha me=[sort(%0)]
  > say [munge(sort_alpha,v(places),v(dbrefs))]
& @decompile
  @decompile <object>[/<wildcard>] [=<newname>]
 
  This dumps the sequence of commands needed to recreate that object. It
  is useful for keeping off-MUSH records of your valuable objects, and for
  transferring code from one MUSH to another. If you specify <newname>, then
  the commands dumped will set attributes, locks, and flags on an object named
  <newname> and will omit the command to create the object.
 
  If <wildcards> are specified, only the specific attributes for the object
  will be printed in decompile format. This allows you to decompile objects
  that are larger than the output buffer limit, as well as simply decompile
  parts of objects; if a wildcard pattern is given, only attributes will be
  dumped (no flags, etc.)  The wildcard pattern is identical to the type 
  used by the 'examine' command and the 'lattr()' function.

& Patchlevel
 
User-visible changes in TinyMUSH 2.2
 
Type 'help patchlevel <patchlevel>' for that list of changes.
 
   2.2.0    (3/22/95)
   2.2.1    (6/04/95)
   2.2.2    (2/13/96) 
   2.2.3    (11/17/96)
 
& Patchlevel 2.2.0
 
TinyMUSH 2.2.0 is the initial release of TinyMUSH 2.2.  It is based upon
TinyMUSH 2.0.10p5. Thus, this list of changes is based off the baseline
2.0.10p5 code. Because this list is quite extensive, it has been broken
up into several sections. See 'help patchlevel 2.2.0 <whatever>' for 
more details on these user-visible changes.
 
     Features     Functions
 
& Patchlevel 2.2.0 Features
  
- Quotas can be managed by object type.
- There is support for multiple guest characters.
- There is support for global aconnects and adisconnects.
- @shutdown/abort causes the game to coredump via abort().
- @pemit has a new switch, /list. @pemit to disconnected/pagelocked players
  no longer returns an annoying error message.
- @decompile can take wildcards.
- 'examine' shows more attribute flags. More individual attribute flags
  are now settable.
- @sweep command notes 'audible'.
- Idle/Reject/Away messages now take the paging player as the enactor,
  rather than the target player. This enables personalized messages.
- @list options and @list process have been reorganized.
 
& Patchlevel 2.2.0 Functions
 
- and() and or() stop evaluating when a conclusion is reached (thus
  increasing their speed. One must be careful of inline setq()s, though).
- hasflag() can now check attribute flags.
- iter() and parse() evaluate their delimiter args.
- lnum() can now take a range argument, and a separator.
- locate() can now taken an 'X' parameter (to force an ambiguous match).
- %q-substitution for r().
- %c/v(c) substitution for 'last command'.
- New functions: default(), edefault(), udefault(), elements(), findable(),
  foreach(), grab(), hasattr(), isword(), last(), matchall(), mix(), 
  munge(), objeval(), ports(), scramble(), shuffle(), sortby(), squish(),
  ulocal(), visible()
 
& Patchlevel 2.2.1
 
- ZONE flag allows parent rooms to become local master rooms.
- @dolist/notify queues a '@notify me' at the end of a @dolist. 
- building_limit conf parameter restricts total size of the db.
- @list options gives output limit, as well as the new parameters.
- Mortals can now @destroy exits they're carrying.
- setq()/r() values should now be "protected".
- matchall() with no match returns a null string, rather than a 0.
- shuffle() and squish() with no arg return null strings, rather than errors.
- min() and max() no longer truncate floating-point numbers.
- not() boolean values are consistent with and(), or(), etc.

& Patchlevel 2.2.2
 
- Wiz-settable STOP flag stops $command searching when a match is found.
- Optional COMMANDS flag (require_cmds_flag conf parameter) restricts
  $command searches to objects with the flag set.
- Secondary local master rooms available via @parent/zone (optional,
  with parent_zones conf parameter).
- god_monitoring global parameter for God's command log.
- New functions: andflags(), orflags(), left(), right(), lpos(), 
  objmem(), xcon()
- lattr() works like it did in 2.0.10p5 (using it on a non-existent
  object returns the more logical empty string, not '#-1 NO MATCH').
- map() without a list returns an empty string.
- udefault() correctly evaluates its arguments.

& Patchlevel 2.2.3
 
- Attributes are now alphabetized.
- The BOUNCE flag acts as the equivalent of a @listen of *, letting messages
  pass through an object.
- The lastcreate() function returns the dbref of the last object of a 
  given type created by a thing.
- The no_parse attribute flag prevents the input to a $command from being
  evaluated.
- The NOSPOOF flag is only visible to wizards.
- Wizards can now lock out Guests from certain sites (guest_site parameter).
- Pueblo client support is now available, if enabled.
- mix() no longer eats the beginning of null output.
- @sets of the form '@set foo=bar:_baz/boom' now work properly.
