That is a good RFE. >If you think this would be beneficial, please vote. I have. Only once! I want to vote 1 million times, but no... ;-) J.P. wrote: >"Your request is not going to end well. " Really? This is an enhancement. Currently the logic is from youngest to oldest, but she wants to reverse the reading from the oldest to youngest. I believe there is a table (in the address space) used by that access method which gets all the GDG versions and then list them one by one based on available catalog entries and JCL DD entries at STEP level. After that, that list is then made available to the program in the JCL. All she asks is, simply reverse the order in a control block or area where that GDG version lists are stored temporarily.

Lizette wants the oldest and the access method should find that oldest entry no matter what the quantity of versions there are. Currently as John said, only method is to get the GDG base, get the # of versions and move on from oldest to youngest. Tedious, but only method available which may or may not meddle with that DISP=(OLD,DELETE). Good luck Lizette, you will need all the help. I remember your previous posts on this subject.
