it my understanding the first 12 bytes is the allocated block descriptor However when I do a VSMLOC on that address I get nothing return in the TCB= field This clearly is not real data from the VSMLIST that has been shown. Why did you have to make up data? There cannot possibly be a x'1000'

Joseph, The example address you posted looks very much like LSQA to me - are you sure it was returned by VSMLIST SP=PVT ? Also - did you check the return code from VSMLOC? Might be worth capturing a in-flight dump of the target address space and comparing what you are seeing with IPCS VSMDATA

 ALLOC means GETMAIN/STORAGE OBTAIN I mean I understand that z/os always gets in increments of 1K or 4096 so free means it was part of the storage z/os obtained but the user didn’t request so the storage that the user requested really starts at 7FF9CE28 right ? > On Jul 21, 2022, at 10:28 AM,

It appears that VSMLIST is documented as not returning the TCB address for LSQA subpools because it treats all LSQA as address space level LSQA. One can wonder why, but it is documented. On Sun, 30 Jul 2017 09:37:53 -0400 Joe Reichman <reichman...@gmail.com> wrote: :>Sorry Binyamin :&
