I would like to clarify a item or two that I mis-stated in a previous email, Haven't used PDSE, most PDS and they were in the linklist, The only time I have seen them compressed is during system time, during a maintenance Window with qualified folks, secondly if they are paying the bucks, well what can I say, I usually was just a hired gun. Especially working for IBM as a consult, which I have numerous times.
