  In reference to the question about resetting variables after a program;
I always write my programs to restore the Ymax, Ymin, Xmax, and Xmin.  I
put these commands in at the beginning (before EVERYTHING else)
Xmin -> T
Xmax -> U
Ymin -> V
Ymax -> W
Then the las thing the program does is:
T -> Xmin
U -> Xmax
V -> Ymin
W -> Ymax

This has the problem that variables such as AxesOn are not restored.

This leads me to another question though.  In the Casio graphing calculators,
you cannot use the variables X and Y in a graphing program because the
calculator stores the current X and Y values there.  I have not tested to
see if TI's have the same problem (mailny because my Casio trained me to stay
away from those variables) does anyone out there know?
