I'm going to work on JDs problem some more, but I'm calling the
whole contest off. Have you ever noticed that you learn more
about IDL when you *think* you know what you are doing, but
you don't?

I thought about sending a book to everyone who submitted a
better solution than mine, but it turns out I don't have that
many books in my library! :-)

Anyway, I've learned that there are at *least* three or four
different ways to solve my original problem. I'll announce the
winners shortly.
