Many thanks for the tutelage, Noreen - I was able to find the old thread, as you directed, and subsequently found exactly what I had originally asked about ! For over a year, I've appreciated (vicariously) the immense wealth of knowledge, wit, and wonder that flows so copiously from the members of Mudcat. This had been my first request for assistance, and I must say that you all came through royally ! Thanks again to all who helped ! Murph
