Ooops -- I posted that message, then lost track of the thread. I apologize. I'll get you a book -- gratis -- as soon as I can find your address. I often stay away from Mudcat for a week or more at a time, and, if a thread falls "out" in that time, I don't see that replies were posted. E-mail would have been better, I think. Did I include my e-mail address in the posting? It'd be like me not to, of course!
