Thanks, Tim. This is new to me. I read it over, but I did not see right away how to issue a line command (such as an F at the left) in the batch. When I get a chance, I'll delve a little deeper and try some tests. But it probably would be simpler if I could discover the program that the F

I think they are talking about two different things here. 1) recapturing the de-occupied space in the data portion of a PDS 2) consolidating the multiple extents of a PDS 1) Unless things have changed a lot, PDS inserts and replacements, and even those of the same size, always get put at

Re: PDS compression needs a new name - defoam? unfoam? degas? I hope someone has a better idea!

The somewhat analogous process for KSDS called "reorganization". But I've heard "de-gas" used, albeit not formally. I have to dispute your contention that calling it "compression" is no longer an option. Changing general usage is generally not an option :-). sas On Wed, Dec 21, 2022 at 6:17

The DADSM PARTREL macro might do this although the documentation isn't explicit. I have a vague recollection that what you ask is possible and that this might be the underlying service needed. It is used by DFSMSdss RELEASE so should be easily testable. On Wed, 21 Dec 2022 at 09:23, David Cole

To be consistent with rearranging file extents on DASD, it would be more appropriate to call it a "defrag", or borrow VSAM terminology and just call it a "reorganize".     Joel C Ewing On 12/21/22 05:16, David Cole wrote: The notion of "PDS compression" has a long and time honored history...

Have a look at the DADSM PARTREL macro. I have a recollection from long ago that a service to release free space without opening a data set (and so updating the last use and last reference date) had been made available and I suspect this might be it. It's used by the DFSMSdss RELEASE command
