1 12      ** Welcome to XYSee **
      ======================

 [Start]: This is the entry point for
 plotting your functions.

 <ACCEPT><ENTER> to view the Family
 Menu selections.

 Note: Select the Tutorial Icon for
 a demonstration of XYSee's many
 exciting features.
2 10 [Puzzle]: This is the entry for
 solving your puzzles.

 Puzzles are combinations of inter-
 woven functions. The challenge is
 to select variables and values to
 match those of displayed "pieces".

 <ACCEPT> to view a directory of
 available puzzles.
3 12 [Macro]: Macros are disk files
 containing commands which emulate
 manual keyboard sequences.
 Macros can replace small, fre-
 quently used routines or automate
 large and complex presentations
 such as the "Tutorial".
 Use the XYSee "smart" editor to
 create and change your macros.

 <ACCEPT> to view a directory of
 available macros.
4 12 [Edit]: Create, change, and
 validate your XYSee macro and
 puzzle files with this easy to use
 application-sensitive editor.

 Additional Help is available on
 macro/puzzle commands and syntax
 (format) requirements, as well as
 on using the editor's keys.

 <ACCEPT> to view the Edit Menu
 selections.
5 6 [Setup]: Configure XYSee to your
 individual requirements for color,
 sound, and data file location, etc.

 <ACCEPT> to view the Setup Menu
 selections.
6 9 [Exit]: You may terminate XYSee's
 current session from here.

 <ACCEPT> to leave the program and
 return to the DOS prompt.

 Note: As you exit, you may save
 the current program configuration
 for use in a future session.
7 8 [Sketch Pad]: Mathematics is not
 only useful, it can also be
 beautiful!  Each sketch is based
 upon a particular family of
 functions.

 <ACCEPT> to view the different
 sketches.
8 10 [Update]: Plot displays are defined
 by values assigned to variables.
 The assigned values affect the
 form, position, and orientation of
 the displayed function.

 You may investigate the effects of
 these changes with this option.

 <ACCEPT> to change variables.
9 8 [Cursor]: Use the cursor as a
 visual indicator for identifying
 points of interest on the display.
 The position of the cursor can be
 changed by pressing an arrow key,
 or by sliding the mouse.

 <ACCEPT> to activate the cursor.
10 11 [Program Help]: General information
 is available on subjects, such as
 starting XYSee, solving puzzles,
 plotting, and using the editor.

 <ACCEPT> to obtain information on
 using the indicated XYSee feature.

 Note: The "Tutorial" also provides
       context-specific, as well as
       general program help.
11 11 [Report]: Each function is asso-
 ciated with various statistics.
 XYSee attempts to calculate as
 many of these as possible.  In
 some cases, terminology has been
 selected to introduce common eng-
 ineering usage (amplitude-offset-
 frequency, etc.).

 <ACCEPT> to view statistics for the
 current function.
12 8 [Model]: Formulas can be expressed
 in various levels of complexity.
 For example, Y=X can be expanded
 to Y=AX, or even Y=(AX)+B to match
 individual requirements.

 <ACCEPT> to view the Model Menu
 selections.
13 10 [Print]: The current plot display
 can be copied to your graphics
 printer. Common EPSON(tm), IBM(tm),
 and HP(tm) compatible formats are
 supported.  If your printout app-
 ears chopped or distorted, try a
 different printer selection.

 <ACCEPT> to view the Print Menu
 selections.
14 11 [Pause]: Your selected puzzle is
 NOW ACTIVE.  Your next step is to
 study the display and pick out all
 the different functions (pieces)
 to be solved.
 You might want to list the pieces
 on a sheet of paper and cross (X)
 them off as you progress.

 <ACCEPT><CANCEL> to view Function
 Menu (puzzle piece) selections.
15 10 [Color Sets]: These predefined
 screen designs and color sets are
 mainly for use with color monitors.
 The monochrome selection is best
 suited to gray-scale monitors and
 laptop computers which require en-
 hanced contrast displays.

 <ACCEPT> to confirm the current
 color set selection.
16 7 [Save]: Transfers the current
  status of the active puzzle to
  a disk file named "XYSAVED".

 <ACCEPT> to save the current
   puzzle or to confirm over-
   writing a previously saved one.
17 6 [Report]: <ACCEPT> to view a puzzle
 complexity and solution status
 report.

 Note: You may print a date-stamped
 copy of the report.
18 11 [Zoom]: It is possible within the
 numerical limits of XYSee to plot
 functions partially, or even
 entirely outside the range of the
 display.
 In attempting to identify these
 "hidden" functions, you may need
 to change the display scale.

 <ACCEPT> to view the Zoom Menu
 selections.
19 8 [Outlier]: This feature highlights
 out-of-tolerance values which can
 cause a solution attempt to fail.
 The "Outlier" is used to "lock-in"
 correct values while attempting to
 "zero-in" on incorrect ones.

 <ACCEPT> to identify the outliers.
20 10 [Data Drive]: XYSee normally
 expects to find macro, puzzle, and
 program files in the same location.
 You may separate your macro and
 puzzle data files from the program
 files by selecting this alternate
 location.

 <ACCEPT> to confirm the current
 location for your data files.
21 12 [Tutorial]: XYSee's many exciting
 features are highlighted in this
 continuously looping macro routine.
 Take a few moments to become fam-
 iliar with the power & versatility
 you may apply to your educational
 endeavors.

 <ACCEPT> to start the tutorial.

 During execution, <CANCEL> to
 stop the tutorial.
22 12 [Save]: XYSee can combine the
 contents of two or more plot dis-
 plays for on-screen comparison.

 <ACCEPT> to save the contents of
 the currently active display.

 Note: The plot scale in effect
 when an overlay is saved is re-
 established upon restoration, and
 any currently active display will
 be automatically rescaled.
23 9 [Overlay]: <ACCEPT> to overlay the
 current display with the contents
 of a previously saved plot.

 Note: The plot scale that was in
 effect when the overlay was saved
 will be reestablished. The current
 active display will be rescaled to
 the new value automatically.
24 9 [Sound ON/OFF]: Context-sensitive
 audio enhancement for dialog boxes
 and puzzle solution rewards, etc.

 <ACCEPT> to toggle sound ON or OFF
 to suit your current environment.

 Note: All Setup Menu selections
 can be saved upon exiting XYSee.
25 10 [Set Colors]: Several predefined
 screen designs and color sets are
 available including monochrome.
 The enhanced contrast of mono-
 chrome may suit gray-scale moni-
 tors (laptops, page-whites, etc.)
 and screen capture needs best.

 <ACCEPT> to view the Color Menu
 selections.
26 10 [Files in]: XYSee normally expects
 to find macro, puzzle, and program
 files in the same default ("X:")
 location.  If you wish to separate
 your macro and puzzle files from
 XYSee's program files, you must
 specify their new location here.

 <ACCEPT> to view the Drive Menu
 selections.
27 10 [Icon Titles]: Icon figures may be
 displayed with or without titles
 that help indicate their function.

 Select "ICON+TITLE" until you are
 thoroughly familiar with the many
 features of the program.

 <ACCEPT> to toggle Icon Titles
 ON or OFF.
28 10 [Model]: Formulas can be expressed
 in various levels of complexity.
 For example, Y=X can be expanded
 to Y=AX, or even Y=(AX)+B to match
 individual requirements.
 You may adjust the current formula
 complexity by selecting this model.

 <ACCEPT> to confirm the current
 model selection.
13 10 [Print]: The current plot display
 may be copied to your graphics
 printer. Common EPSON(tm), IBM(tm),
 and HP(tm) compatible formats are
 supported.  If your printout app-
 ears chopped or distorted, try a
 different printer selection.

 <ACCEPT> to view the Print Menu
 selections.

29 11 [Reset Setup]: XYSee saves current
 formula models and configuration
 changes in an initialization file
 for use during future sessions.

 <ACCEPT> to restore the standard
 program configuration.

 Note: Be sure you save the new
 (standard) configuration as you
 exit XYSee.
30 12 [Variable Values]: Update your
 plot values at this point.

 <ACCEPT> to open a plot value
  entry cell.
