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.
