RE: V5R1 Library List Enhancement (was: PRTCMDUSG RTVJOBA) -- MIDRANGE-L



Actually, it would be nice if some vendors would keep thier AS400
production code version functionality at the same level as the NT, unix,
etc., versions which tend to get currency BEFORE the 400!  Kinda give you
a hint of any sort folks??
