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.
