I apologize for the long ping time on this -- for whatever reason I didn't get any of the replies sent to my email and I thought no one had responded.
JCG, Jack, thank you very much for taking the time. Jack: I had to stare at your code for a while before I got it, but thank you for it. That's really elegant, which is exactly the sort of thing I was looking for. Much appreciated. Dave -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
