Re: does anybody know IDL?
Hrmm.. not sure. I'm beyond rusty, so I don't have a whole lot of insight. But if it works if you type in the prompt, but not as a program, it might be a variable scope thing. Like datainfo might not be being created/populated/accessed correctly from within the program. You might have to initialize it before you call ctm_get_data, for instance. Not sure, though. This is one of those things I figure out by playing with it for a while.
