Load library members have imbedded channel programs. Moving a load library to an FBA disk might have been a challenge. All partitioned datasets have keyed directory blocks. VTOCs are keyed datasets (or were, I don't how the newer format introduced with the DF products worked). However, VSE has the same VTOC format. -- Cheers John Summerfield Microsoft's most solid OS: http://www.geocities.com/rcwoolley/ Note: mail delivered to me is deemed to be intended for me, for my disposition. ============================== If you don't like being told you're wrong, be right!
