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.
