All this horsing around with adding and subtracting 1 had initially led to a mass of confusing code hence the posting of my second message on this subject. Don't bother with that message, it's complete nonsense. By the way, I notice that my messages to this list, and not other's, can take up to four hours (sometimes longer) to appear, is that normal? I'm on a bounces list, is that the reason? Probably not since I'm on several bounces lists. Anyway, enjoy your holiday. -- Regards, Phil _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
