Hi, all: I just posted a reply (in my capacity as a subscriber, not as admin) to the list and forgot to change the subject line. Oops. It is always a good idea to make sure that your subject matches what you are discussing, even if it is a reply, and I forgot. Oh well, if one can't teach with clarity and erudition, one can I suppose always serve as a bad example <grin>. Darrell Darrell A.
