David,
I didn't see 'all_tags' in my documentation for compound widgets. Thanks for
the hint. BTW, I understand the reluctance to use COMMON blocks, but in this
example below, I will have around 25 parameters to return to the calling
program. I'm new to IDL, and I'll have to investigate how to do this without
the use of COMMONS.
Again, thanks for your response.
