Whoops! I thought you had paid for the express service. My
fault. :-)

Ah - I'll keep that in mind in the future. I only really work with IDL
on the command line. Thanks for the replies returned very nearly before
I sent the questions!

You know, I was using that but I didn't think it was working as I was
expecting it to. My bad - thanks!
Bonus question - if I use RETURN a few times, is there a way to print
the stack to see where I am?
Cheers,

I guess I should mention that if you are in the IDL Workbench
the "Debug" window shows you the call stack and by just clicking
on the location you want, you can immediately go to that level.
The "Variables" window will be updated to show the variables
at that level.
Cheers,
David
