Yeah, then you could use your pattern matching software (you
might have to write this yourself, but I'm sure it can be done
in IDL) to find out what symbol it was, and there you would have it.

Oh, gosh. Since it involves a computer, I'd be willing
to risk as much as a dollar. Guess that's about four
of yours, Mark. :-)

Cheers,
