I guess I should mention, too, although you probably
already realize this, that I have a REVERSE keyword
defined for the COLORBAR routine. When I enter the
program the *variable* reverse is set to 1. I didn't
mention this before because someone is invariably going
to point out that I also have an INVERTCOLORS keyword
defined that does the very same thing as my REVERSE
keyword and why the hell do you have TWO of them defined!?
I just didn't want to get into all that. :-(

But the fundamental question still remains. Why does
that line above confuse IDL about what REVERSE is?

Cheers,

David
