I've been thinking lately that either we need a refresher
course in how to ask technical questions, or my mind is going
blank faster than I anticipated. Neither prospect is
encouraging to me.

Here is a good place to start if you need a refresher:

http://catb.org/~esr/faqs/smart-questions.html

The section on "Be Explicit About Your Question" might
be a good place to start, if you are short on time.

If you think my mind is going, then join the line. :-(

Cheers,

David

P.S. With respect to *this* question, I'm not sure I
even know which IDL procedure performs the *first* step.
