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

 [Select Plot]: This is the entry
 point for plotting functions.

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

 Note: Select the Run Macro
 option for a demonstration of
 XYSee's many exciting features.
2 11 [Puzzle Menu]: Puzzles are
 combinations of functions
 interwoven on a common display.
 The challenge is to select
 pieces (functions) with
 dimensions (variable values)
 matching the display within a
 user defined tolerance.

 <ACCEPT> to view Puzzle Menu
 selections.
3 12 [Run Macro]: Macros are disk
 files containing commands which
 emulate manual keyboard se-
 quences.  Macros can replace
 small, frequently used routines
 or automate large and complex
 presentations ("Tutorial").
 Use the XYSee editor to create
 your macros ("Edit Files").

 <ACCEPT> to view Macro Menu
 Selections.
4 10 [Edit Files]: Create, change,
 and validate your XYSee macro
 and puzzle files with this
 application-sensitive editor.
 Application command, edit-key
 assignment, and file syntax
 (format) help is available.

 <ACCEPT> to view Edit Menu
 selections.
5 11 [Setup XYSee]: Configure XYSee
 to your individual requirements
 with respect to color, sound,
 and data file location, etc.

 <ACCEPT> to view Setup Menu
 selections.

 Note: Please refer to the
 "Registration" selection for
 XYSee ordering information.
6 9 [Exit XYSee]: You may terminate
 the current session from here.

 <ACCEPT> to return to the Dos
 prompt.

 Note: You may save program
 changes for use as defaults
 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 11 [Update Values]: Plot displays
 are defined by values assigned
 to formula variables.  The
 assigned values typically
 affect the form, position, and
 orientation of the displayed
 function.  You may investigate
 the effect of variable changes
 with this option.

 <ACCEPT> to change variables.
9 7 [Cursor]: Use this visual
 indicator to identify points
 of interest on the display.
 You may reposition the cursor
 with the arrow keys or mouse.

 <ACCEPT> to activate the cursor.
10 9 [Overlay Plot]: XYSee can
 combine two or more plots for
 comparison.  Multiple plots of
 a single function and/or indi-
 vidual plots of different func-
 tions may be combined at will.

 <ACCEPT> to view Overlay menu
 selections.
11 11 [Statistics]: Each function has
 associated with it various sta-
 tistics.  XYSee attempts to
 calculate as many of these as
 possible.  In some cases, ter-
 minology has been selected to
 introduce common engineering
 usage (amplitude, frequency,
 offset, etc.).

 <ACCEPT> to view statistics.
12 9 [Select Model]: Formulas may
 be expressed in various levels
 of complexity.  For example,
 Y=X can be expanded to Y=AX,
 or even Y=(AX)+B to support
 individual requirements.

 <ACCEPT> to open a formula
  model entry box.
13 11 [Print Plot]: The current
 plot display may be copied to
 a graphics printer.  Popular
 EPSON(tm) and IBM(tm) compat-
 ible graphics modes are suppor-
 ted.  If your printout appears
 chopped or distorted, try
 selecting a different mode.

 <ACCEPT> to open a print mode
  entry box.
14 9 [Select Puzzle]: This is the
 point of puzzle activation.

 <ACCEPT> to view a directory
 of available puzzles.

 <CANCEL> to abort an active
 puzzle (if confirmed) and
 return to the Main Menu.
15 6 [Solve Puzzle]: This is the
 entry point to solve an active
 puzzle ("Select Puzzle").

 After activation, <ACCEPT> to
 view Family Menu selections.
16 7 [Save Puzzle]: Saves remaining
 pieces of the current puzzle
 to a disk file - "XYSAVED".

 <ACCEPT> to save the current
 puzzle or confirm overwriting
 a previously saved one.
17 6 [Puzzle Report]: <ACCEPT> to
 view a complexity and solution
 status report for your puzzle.

 Note: You may print a copy of
 the report if desired.
18 12 [Zoom Scale]: It is possible
 within the numerical limits of
 XYSee to plot functions par-
 tially, or even entirely out-
 side the range of the display.
 In attempting to identify these
 "hidden" functions, you may
 need to change the display
 scale.

 <ACCEPT> to open a zoom scale
  entry box.
19 9 [Show Outlier]: This feature
 highlights out-of-tolerance
 values which can cause a so-
 lution attempt to fail.  "Show
 Outlier" is used to "lock-in"
 correct values while attempting
 to "zero-in" on incorrect ones.

 <ACCEPT> to highlight outliers.
20 12 [Select Macro]: Macros are disk
 files containing commands which
 emulate manual keyboard se-
 quences.  Macros can replace
 small, frequently used routines
 or automate large and complex
 presentations ("Tutorial").
 Use the XYSee editor to create
 your macros ("Edit Files").

 <ACCEPT> to view a directory
 of available macros.
21 12 [Tutorial]: XYSee's exciting
 features are highlighted in
 this continuously looping macro
 routine.  Take a few moments to
 become familiar with the power
 and versatility you may apply
 in your educational endeavors.

 <ACCEPT> to start tutorial.

 During execution, <CANCEL> to
 stop the tutorial.
22 12 [Store]: XYSee can combine two
 or more plots for comparison.

 <ACCEPT> to store the currently
 active display.

 Note: The plot scale in effect
 when an overlay is saved is re-
 established when the overlay is
 restored.  Any currently active
 display will automatically be
 rescaled to the new value.
23 10 [Restore]: <ACCEPT> to overlay
 the current display with a
 previously stored plot.

 Note: The plot scale that was
 in effect when the overlay was
 saved will be reestablished.
 Any currently active display
 will automatically be rescaled
 to the new value.
24 5 [Sound ON/OFF]: Context-
 sensitive audio enhancement.

 <ACCEPT> to toggle sound on or
 off to suit your environment.
25 10 [Set Color]: Four predefined
 sets of colors are available
 as well as monochrome.  The
 enhanced contrast of monochrome
 may suit gray-scale monitors
 (laptops, page-whites, etc.)
 and screen capture needs best.

 <ACCEPT> to open a color set
  entry box.
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 data
 files, you must specify their
 new location with this option.

 <ACCEPT> to open a data drive
  entry box.
27 11 [Configure Dos]: Sets up your
 operating system to support
 special requirements of XYSee.

 <ACCEPT> to check for a system
 "CONFIG.SYS" file containing a
 FILES=20 statement.

 Note: After confirmation,
 XYSee will create or alter the
 file as necessary.
