>Thanks, Bruce. The biggest problem with the Quick is the implementation. It is not easy to understand. Right now, I'm trying to work one up and it's a major PITA. Hopefully, I'll have it done during lunch and post it (with the others) here.

I've used the recursive Quick in several statistical programs here, some years back before we went fox. Don't have them handy any more, but I remember I basically copied from textbooks and modified a little as needed :)
