No Iam sorry I have no solution to this but I will show you some trouble
you got if you don't save some system variables
tek_color
window,1,xs=100,ys=200
plot,findgen(100)
window,2,xs=200,ys=100
plot,findgen(100)
wset,1
oplot,findgen(100),color=4
wset,2
oplot,findgen(100),color=4
oplot on window 1 gives no blue line.
IDL stores always only for the last plot in !x, !y and so on
the parameters which are necessary needed to add some plots later.
We have two useful routines in our library to get out of this trouble.

Yep.
IDL> FSC_Window, 'TVImage', Indgen( 256, 256)
Resizeable graphics window, automatic output to
all kinds of file output, color tables built
in, etc., etc.
You can find all the programs you need on my
web page. :-)
Cheers,
David

OK, I guess I asked for it :-) I'll check the books (including yours; I
bought that a couple of weeks ago too :-)
Just for some encouragement before I try this, is there an easy way to
translate something like
window
tvscl, indgen(256,256)
into 'widget speak'?
Thanks,
Andrew

Let me just say that if IDL were written as an environment where everything
*had* to be done as a widget program, we probably would *not* be using IDL
today. We'd be using something else more forgiving. And I say this as someone
who's written a fair number of widget programs in his time.

I'd add the !Map system variable too, if I wanted
a completely general solution. :-)
