Yes, you're right about REQID. I use the default, so I had forgotten. David Logan

Not true. Look at the REQID parameter. And a STARTBR in a particular transaction is independant of all other transactions' STARTBR request(s). So the ENDBR in a transaction refers to the __single__ STARTBR in that transaction. Or the STARTBR in the same transaction with the corresponding REQID parameter, if any is specified. REQIDs are unique only within a given transaction. > > The logic doesn't really make sense. What would the > underlying strings be > doing other than "being unreachable/being unusable"? Strings are used in VSAM to "hold position". That is what the string used by a STARTBR would be doing. It would be holding the VSAM position within the file for the corresponding READNEXT or READPREV. > > David Logan -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
