HELP,<return_string>=<variable of interest> ??
A while ago someone discussed using help,calls=calls to get the traceback info from IDL as a string array. It works. Does anyone know if I can get the normal HELP info on just a simple variable back similarly, as in: help,var=var or maybe help,/stru,struct=some_struct I have a large structure, and I really like the output of 'help,/stru,my_struct', so why can't I get it as a string array? Or is there some undocumented backdoor for this...?

RSI (thank you Steve Penton) saw my post and sent me the source code to GETHELP function. I thought it got posted to the group as well, but if anyone sends a request to me I'll repost it. It is great; just what I wanted, and educational to peruse. Russ Welti
