All line  ││ oriented commands such as compilers and linkers will  ││ work OK. Some programs will trash you royal, use      ││ the "exit to DOS" function αF2 for these.             │└───────────────────────────────────────────────────────┘Exit to DOSSaves the file; keeps Blackbeard memory resident and returns toDOS.  To return to Blackbeard type EXIT at the DOS prompt.Backup fileCopies the current file to a file with the same name, but with a .BAK extension.Blackbeard can create a backup file, at startup.  Blackbeard willcopy the original file to a .BAK file.  While editing, Blackbeardwill page your file in and out of memory.  If the computer shouldcrash while editing; the edited file may be unusable.  The defaultis not to provide a backup file.   Automatic backup can be turned on by using the options flag      Auto backup - ON indicates that a backup of you file is      written to the same filename with a .BAK      extension when you edit the file.  OFF means      no backup is made.Kill windowThe kill window contains deleted text, which is edited like anyother window.ExpandExpands the current window to a full screen.SelectDisplays a pop-up menu of windows and their files.Select the window desired.  Esc to stay in the currentwindow.Frame/MoveMoves the current window.Frame changes the size of the window by moving the lower rightcorner of the window.  Enter switches modes.  Esc completesmoving/framing.Edit ScreenEdit screen allows you to review the screen that was present beforeBlackbeard fired up. You can perform the following functions.   Mark start and end using your mark keys.   Unmark the region.   Clear the paste buffer.   Grab text using the grab key.   Goto file using the goto file key.Color/B&WTurns color on and off.If you are using the IBM monochrome adapter or a color/graphicsadapter with a color monitor, you will not have to configureBlackbeard for your system.  If you are using Blackbeard with acolor/graphics adapter and a monochrome monitor, you will have toconfigure Blackbeard so that it does not use color.  To do thisrun Blackbeard, press αF9 (to turn off color) and save yourconfiguration using the configuration menu.Select colorOptionsThese are configuration items that are toggled:   BLINKING = ON  = SELECTED   NORMAL   = OFF = not SELECTEDPosition cursor and press <ENTER> to toggle.Help is available for each item.BulletSet an indent column for word wrap.  Wrapped words are be indentedto this column rather than the first column or current line'sstart column.  Bullet mode is for making bullet charts where thefirst line of each topic starts indented left of the text, andusually begins with a circle ( letter O ), and therefore lookslike a bullet was shot at the page.ASCII chartDisplays an ascii chart with DECIMAL, HEX and Character.  Scrollthe chart with the left, right, up and down arrows.  Esc to exit.Delete lineDeletes the current line to the Kill buffer.End of linePlaces the cursor at the end of the line.  This may involveshifting the window to the right.FindSearches the file for a string.  It searchs forward from thecurrent position to the end of the file.  You can enter specialcharacters into a search string by pressing the control key orusing the Alt key and the numeric keypad.  Esc and Enter abortsearching.  To enter the character code for Escape use the Alt keypad (in num lock mode) and enter 27 (the code for escape). For reqularexpressions see help 200.GotoGoto a specified line of the file.  If the line is greater thanthe number of lines in the file, END OF FILE is performed.BackspaceDeletes the previous character.  If the cursor is at column one,nothing happens.TabMoves the cursor to the next tab stop.  If tab insert is on thenspaces are insert up to the next tab stop.ReturnShifts the window to the left edge and place the cursor in thefirst column and down a line.Break lineBreaks the line at the current cursor position.Insert lineInserts a line at the current cursor positon.Return & insert linePerforms RETURN and INSERT LINE.New fileOpens a new file to edit in the current window.  If no filename isgiven, a pop-up menu displays a directory.  Wildcards in thefilename can constrain the directory.  Select the file to editusing the standard menu keys.  Esc if you do not want to select afile.Tab leftMoves the cursor left to the next tab.Adjust paragraphReformats from the beginning of the current line to the next emptyline or the end of the file using the current right margin and theindention level of the following line.  This allows the first lineto be a different format than the rest of the paragraph.Insert special charInserts any ascii character specified by number.  This is veryuseful for putting in special printer escape sequences.  The ALTkey and the numeric keypad can also perform this function forcertain characters, but not the Ctrl keys.Find & ReplaceFind a string and replaces one string with another.  Thereplacements can be conditional, meaning Blackbeard will ask youwhether you actually want to replace the string before it replacesit.  Replacements can be global, meaning replace every occurrenceof the string from the current cursor position to the end of thefile.StatusPermits tailoring what is displayed on the status line.The last line of the screen contains the status information.Line  1  Col  0  <DMIWSTN> Kill   0 Paste   0 C:\filename 846   The status line tells you the line and column you are workingon.  The letter inside brackets indicate the current editingsettings.  The possible letters and meanings are described in thefollowing chart:Letter   Meaning   D  Drawing mode on        B  Bullet mode on   M  Keystroke macro           (and word wrap on)      recording on           S  Case sensitive search on   I  Insert mode on         T  Auto-tab on   W  Word wrap on           N  Auto-insert onKill  - followed by the size of the text in the delete buffer.Paste - followed by the size of text in the paste buffer.The name of the file you are editing followed by its size.TransposeSwaps the current character with the next character.Undelete lineInserts a line from the Kill buffer at the current line.  Thatline is deleted from the Kill buffer.Define macroStarts and stops keystroke rememberingDelete to eolDeletes the rest of the line.  Undo will undo this function.Execute macroExecutes the current keystroke macroYank lineInserts a line from the Kill buffer at the current line.  Thisallows multiple insertion of the same deleted line.  It works as aquick cut and paste.ExitSave the current file and exit BlackbeardMenus   To access the menus and learn the commands press the escape<Esc> key and the main menu will pop-up.  You can execute acommand or select any submenus by positioning the cursor on theitem (using the keypad keys or first character of item) andpressing the Enter key.  To exit a menu without choosing an itempress the escape key.  The menu pops up where the cursor wasbefore you entered the menu.  With few exceptions the menucommands have their direct keyboard counterparts described to theright of the English command description.  The direct commands usethe keyboard letters and the shift () , Alt (α), and control(Ctrl) keys.  The following describes how they are shown:     ^R - means Ctrl-R     R - means Shift-R     αR - means Alt-R   The function keys are designated as F1 - F10.Settings   Right margin - Sets the right margin used for word wrap and               paragraph reformatting.   Tab size - Sets the size of tabs for compression and expansion	      8 = default (standard)   Line size - Sets the size of the line for line drawing mode.               0 = dashed line;               1 = single width;               2 = double width.   Case mode - Set the change case mode for change case and change               case region.               0 = Flip case;               1 = Upper case;               2 = Lower case   Insert number - Sets the number to insert with the insert               number function.  The number is always incremented               by one each time it is used.Bullet offTurns bullet mode off.  Bullet mode is for making text charts withthe bullet entries ( as in the help for the MISCELANEOUS menu ).Center lineCenters the line using the right margin settingDelete blockDeletes a marked block.Repeat menu commandRepeats the last menu command.Repeat findRepeats the last search.Switch to filecauses the next vaild file name on current line (file is opend innext window), useful to edit included files in a program.Ruler αA lets you set tabs every [n] columns. 0 means clear all tabs  T toggles a tab setting  L sets a left margin (not used currently)  R sets the right marginJoin lineJoins the next line to the current line.  A space separates thelines.Last DOS commandDisplays the last DOS command executed in the DOS window.Delete macroA menu of named macros appears.  Select the macro you want todelete.Reread fileAdjust blockReformats from the beginning of the current line to the next emptyline or the end of the file using the current right margin and theindention level of the current line.Line drawingBlackbeard can draw lines oriented pictures, using the linedrawing characters.  Think of the line drawing as a crude penplotter.  αQ "raises or lowers" the pen.  When lowered, cursormovements using the keypad cursor keys cause lines to be drawn.The four arrow keys move left, right, up, and down.  The fourcorner keys (1,3,7,9) move diagonally, but the diagonal lines arenot as well formed as the horizontal and vertical line.  Here is asample picture formed by dropping the pen (αQ), moving the cursor,and then lifting the pen (αQ again) in 3 different widths.   +--------------+  ++-+  ┌──────────────┐  ┌┬─┐  ╔══════════════╗  ╔╦═╗   | Line width 0 +--+++|  │ Line width 1 ├──┤└┐│  ║ Line width 2 ╠══╣╚╗║   +--------------+  +-++  └──────────────┘  └─┴┘  ╚══════════════╝  ╚═╩╝Blackbeard supports three line widths: 0, 1, and 2.  The pictureabove is shows the three widths.  Most printers print the linewidth 2 as line width 1 Width 0 draws lines using ASCII char-acters.  The line drawing characters will only print on printerswhich support the (IBM Graphics character set).  If you do nothave such a printer, you can still do line drawing using width 0.The flags on the bottom status line show an I for insert mode.Repeat replaceRepeats the last replace.Status colorSelects the foreground and background color of the status line.Change caseChanges the current chararter's case according to the change casemode.UndoRestores the line to the last edited state.Name macroAssigns a name to the current keystroke macro.Write fileExecute named macroA menu of named macros appears.  Select the desired macro toexecute.  This macro now becomes the current macro.AbortExits Blackbeard without saving the current file.  Useful if youselected a strange file to edit or want to start over.WARNING !!!  If you make a change in part of large file, and thenpage through ( with the "READING" and "WRITING" messages ), then theabort may not do whay you think.  Once the "WRITING" message showsup, the portions currently changed have already been written to disk.This function is really only applicable to small files.  If you areconcerned about this, you may wan't to look at the backup optionavailable ( e.g. forced backup on the FILE menu, or setting theauto backup option on the OPTIONS menu ).Insert numberinsert a number at current cursor position.  the number is thenincremented by 1.  See set insert number in settings menu to setit back to 0.Write bindingsBlackbeard keeps a key binding file that will allow you toredefine the keystrokes: Blackbeard looks in the currentsubdirectory for a file named BB.KEY.  This file defines thekeyboard binding.  If there is not a file named BB.KEY in thecurrent subdirectory, Blackbeard will look in the BB DOSenvironment subdirectory for this file, if it is found it will usethe filename supplied with the symbol.  This will let you keep onekeyboard file and use Blackbeard from any disk or directory.This command will request a filename and default to the currentpath and BB.KEY filename if none is given.Delete wordDeletes the next word forward.Self insertInserts the character.Read bindingsShow bindingsDisplays the current key to function bindings.Repeat keyRepeats a key a selected number of times.  You are prompted forthe repeat count and then the key to repeat.  Useful for repeatingmacros.  To interrupt repeat hit any key.Adjust special Reformats the same as ADJUST PARAGRAPH, except when justifying nospaces are inserted between the first and second word.  This isvery useful for bulletted paragraphs.LNG windowThis will move you to the language window.  The language windowis further described in help message 124.Break & Next LineBreaks the current line and set cursor to next lineInsert fileSearch reverseSearchs the file for the requested string from the current cursorposition backward to the start of the file.Repeat search reverseRepeats the last search reverseGoto start markerMoves the cursor to the start of a block marked by the Mark Startkey.  See the cut&paste menu for the Mark Start command.Expand LNGBlackbead reads in the file BB.LNG (or the file associated withthe symbol BBLNG) if present into a "language" window.  When theexpand language function is executed the symbol at the currentcursor position is looked up in this window.  A symbol isdesignated with either a > or < sign.  If the symbol is designatedwith a < then the symbol is replaced by the set of lines thatfollow the symbol upto the next > or < sign or end of file.  Ifthe symbol is designated with a >, then you are prompted for whichreplacement you want to make from the lines that follow thesymbol.  The current BB.LNG file is for most of ADA.   There is a limit of about 250 lines in the BB.LNG file.This part of Blackbeard is somewhat experimental (not in terms ofreliability but in terms of probability of change).Set DelimitersSets the characters that define what are to be delimiters betweenwords.  Works with right_word, left_word and delete_word and alldelimited command types.  Enter toggles the delimiter on/offHelpThe Blackbeard help facility is available for status line promptsand menu selections.  It is context sensitive.  To view any helpmessage enter the number of the desired help message.Help can be invoked with a ALT-H from anywhere (menus andprompts) Use ESC to exit from help screen.  Prompt help screenslet you view the help while responding to the prompt.if you press ENTER from this help message you will get a completelist of help screens that you may select from; go ahead and lookaround.  Some help screens of interest early on are:         0  running blackbeard        87  direct and menu execution of commands       223  configuration (environment SET commands)Please note that the manual is generated from the BB.HLP anddoes not contain any additional information.Use the ESC key to pop up BlackBeard menusDo CommandThis executes a DOS command.  The command is saved for laterreexecution either with ALT-L directly or in the Dos Window withAlt-L <Enter>.Switch To WindowSwitches to a window and prompts for a file.  The window WILL bedisplayed and not interrupted.  If you want to use the samefilename, use Escape; Enter will bring up a directory offilenames.Print RegionCopies the marked region of text to the PRN device -- i.e., prints it.Print ColumnCopies the marked column of text to the PRN device -- i.e., prints it.Regular Expression Search  \  The backslash quotes any character.  \$ matches a dollar-sign.  ^  At the beginning of an expression matches the beginning of a line.  $  A dollar-sign at the end of an expression matches the end of a line.  .  A period matches any character except \"new-line\".  :a  matches any alphabetic,  :d  matches digits,  :n  matches alphanumerics,  :   matches spaces, tabs, and other control characters, such as      new-line.  *   Following an expression matches zero or more occurrances  +   Following an expression matches one or more occurrances  -   Following an expression optionally matches the expression.  []  Matches any character in that string, but no others.  Range      of characters specified by separating two characters by - [a-z]      Circumflex (^) is the "not" operator (match any not in the string).INSERT/REPLACE FLAGBLINK  insert character modeNORMAL overstrike character modeINSERT_TABSBLINK  right tab inserts spaces up to the next tab.NORMAL right tab moves the cursor to the next tab position.TAB_FLAGBLINK Align the cursor to the column of the current line when      inserting lines, deleting line, return and word wrapping.NORMAL cursor goes to column 1RETURN_FLAGBLINK  Return inserts a blank line (auto-insert)NORMAL goes to the next line.TRIM_SPACES_FLAGBLINK  Trailing spaces are deleted (auto-trim)NORMAL No trimming spaces are leftTAB_COMPRESS_EXPAND_FLAGtab-to-space translation when editing the file.BLINK  tabs are translated to the appropriate white spaceNORMAL tabs not translated, displayed as tab character.WORD_WRAP_FLAGBLINK wrap words typed past the right margin (see SETTINGS) to the       next line (word processing style).NORMAL no wrapping (programmer style)JUSTIFY_FLAGBLINK Perform left justification (by inserting extra spaces) when       word wrapping and adjusting paragraphs.NORMAL no left justificationCASE_SEARCH_FLAGBLINK  all search and replace functions are case sensitiveNORMAL ignore case when searching or replacingSEARCH_MODEBLINK  indicates "regular expression" searchingNORMAL indicates normal searchBACKUP_FLAGBLINK indicates that a backup of your file is written to the same      filename with a .BAK extension when you edit the file, safer.NORMAL means no backup is made, updates are inplace, faster.CURSOR CONTROLsub menu of commands to control movment of the cursor on thescreen and thru the file.FIND & REPLACEsub menu of commands to find and or replace character stringsCUT & PASTEThere are two types of regions: columns and ragged text.  Forragged text, "mark start" marks the start of a region, and "markend" marks the end of a region.  If "mark start" is pressed withthe cursor position after the marked region it extends the region;the converse is true with respect to "mark end." Try it and youwill get used to how it works; it works like you would expect itto.COLUMNS   There are two types of regions: columns and ragged text.  Forcolumns, "mark start" marks the upper left corner and "mark end"marks the lower right corner of the block.WINDOWSBlackbeard is a windowed editor with 13 windows; 10 for normalediting, and three for special purposes.  You can edit one or morefiles in the general editing windows.  To edit a different file ina window just bring up the window using Ctrl and one of thefunction (F1-F10) keys and press ^N to edit a different file.Note that this does not affect any other windows; only the currentwindow you are in.  The current file will "follow you around" tothe un-initialized windows that you move to.  You can select,re-size, and color windows from the window sub menu.  ┌─────────────────────────────────────────────────────────────────┐  │                  Windows and their default sizes                │  ├──────────────────────────────────────┬──────────────────────────┤  │  ^F1 - Main window; full screen      │    αF1 - DOS window      │  │  ^F2 - full screen                   │    F10 - Paste window    │  │  ^F3 - full screen                   │    αF4 - Kill window     │  │  ^F4 - full screen                   │    α0 - Language window  │  │  ^F5 - top half of screen            │                          │  │  ^F6 - bottom half of screen         │                          │  │  ^F7 - left half of screen           │                          │  │  ^F8 - right half of screen          │                          │  │  ^F9 - left half of screen           │                          │  │  ^F10 - right half of screen         │                          │  └──────────────────────────────────────┴──────────────────────────┘EDITMACROSOne of the most powerful Blackbeard features is the keystrokemacro capability invoked by pressing ^V.  When ^V is pressedBlackbeard starts remembering keystrokes that you press until ^Vis pressed again (the number of keystrokes remembered is about500).  To reexecute this remembered sequence of keystrokes press^X.  Blackbeard allows you to name your macros; delete macros youhave named; execute named macros; save the macros to a file andread them back in.WORD PROCESSINGOPTIONS/SETTINGS/KEYSThe options/settings/keys menus provide a way to tailor theBlankbeard environment.  Functions are also provided to managethe selected environment ( save and restore of standard settings ).The meanings are:   Options  are attributes about the way Blackbeard behaves (such	    as character overstrike, tabbing, and word processing)   Settings allow you to set values for parameters such as right margin	    and line drawing widths.  This also allows for selecting	    the Jolly Roger logo at startup.   Keys     provides access to the key redefinition utility.All of the items in options and settings are saved in theconfiguration file (BB.CFG).FILEThis provides several file/buffer management functions such asrereading a file, saving to an alternate file, and inserting afile into the current file.MISCELLANEOUSThis is a menu of assorted functions including capabilities to:   o  Access DOS   o  See the IBM PC ASCII Chart   o  View the tab ruler   o  Line drawing   o  Language expansion support   o  Other special featuresCONFIGURATION INFORMATIONAt startup Blackbeard looks for the following optional files:   FILE     DESCRIPTION               FILE SEARCHING ORDER   ------   -----------------------   ---------------------------------   BB.CFG - Configuration file.       current dir, BBCFG, BBDIR   BB.KEY - Key binding file.         current dir, BBKEY, BBDIR   BB.MAC - Macro file.               current dir, BBMAC, BBDIR   BB.PST - Paste file.               BBPST, or internal paste buffer   BB.LNG - Language file.            current dir, BBDIR   BB.HLP - help file (this text)     BBDIR, current dirplace any needed SET commands in your AUTOEXEC.BAT file.note that you may only need to use BBDIR and BBPST   SET BBDIR=<directory> for example:  SET BBDIR=C:\BB   SET BBCFG=<filename>  for example   SET BBCFG=D:\bb.cfg   SET BBKEY=<filename>  for example   SET BBKEY=D:\bb.key   SET BBMAC=<filename>  for example   SET BBMAC=D:\bb.mac   SET BBPST=<filename>  for example   SET BBPST=D:\bb.pstThis allows you to keep one BlackBeard configuration and useBlackbeard from any disk or directory.Blackbeard File HandlingBlackbeard uses a virtually virtual memory method to handle largefiles.  This means it pages the file in and out of memory.  Themessages Reading file and Writing file appear on the status lineto indicate when Blackbeard is paging the file.  Blackbeard usestwo buffers to keep track of your file.  One that keeps trackof every line in the file and one that pages your file in andout.  Blackbeard's file size is limited by the number of lines.The default is about 8000 lines (this is large enough for almostall text files).  However, you can tell Blackbeard how todistribute its vitrual memory buffers.  The line buffer's sizeranges from 4000 to about 24000.  The default is 8000.  It shouldbe set to the maximum expected file size (in terms of lines) youwill edit.  To set the line limit run Blackbeard with either ofthe following commands:   BB =# of lines   or    BB <filename> =# of lines   Example: BB read.me =20000Will run Blackbeard such that it can accept files that have up to20000 lines.Prompt line editingWhen Blackbeard prompts you for information.  You have limitedline editing capabilities.  These include the right and left arrowkeys, the backspace and delete keys.  The up arrow will recall thelast entry if it is available, it works for any Filename, Searchand Replace.   For the filename prompt a directory list is available with the   Enter key.   Esc always bails you out of the prompt.αH (the help key) will bring up this screen or a more specificscreen if there is one.SAVE/RESTORESave/Restore option allows "warm start" using the save file.Window status is saved to BB.SAV file in BBDIR directory.  Thisfile is checked for when Blackbeard starts.Number of rowsAllows you to select the number of rows that are displayedon the screen. This is especially useful for EGA43 mode andVGA 60 line mode
