Datastream, took you up on that assignment and found if folks read these selected posts in he following order they might find them to be most informative. Starting with post 31611 " read all my posts" ending with post 30932 " I was there". Next, read the following posts in this order....31115, 31569, 31278, 31438, 31611, again 30937. Recall the show in the 50's "What's My Line"? I ask the Peanut Gallery. Well? A hint read the last post to me from Datastream,to which I made no response but do so now. Totally agree to your response, most important.
