My goodness! 15 years I've been writing IDL programs and
finally one or two people are using them! You can't imagine
how excited I am. :-)
Well, FSC_Surface was written more or less as a direct
substitution for the Surface command. You don't necessarily
have to kill the window to visualize another surface. Just
start up another FSC_Surface command:
IDL> FSC_Surface, dist(40)
IDL> FSC_Surface, Findgen(30)#Findgen(30)
The two windows operate independently.
There are any number of problems with switching
the data in the program. Primarily because this
is an object graphics program, which means NOTHING
is all that easy. It is not a matter of just switching
the data in the IDLgrSurface object. I would also have
to re-scale all the axis objects, recompute the font
objects, etc. It's possible, but the non-object format
of the program itself discourages the attempt.
On the other hand, do you have any money
for the deluxe version? :-)

What would you do with it if you got it? Have you
worked with any object graphics programs before?
This would not be as useful to you as you might think,
I expect.
Cheers,
David
