Peter You are right while doing my analysis
I found some erroneous data returned not really erroneous But I did screen print so it’s not made up The allocated block address is FF7A5000 Looking at the doc mapping macro IGVVSMD for the block descriptor it’s VSMDBLK DS A Now I know that address is really 7F7A5000 In the mapping macro there is no EQU for the high order bit what significance it is But I know you know the answer hoping you can share In addition would be nice nice if IARV64 REQUEST=LIST Would return this type of info But you said I could open an RFE Thank you > On Sep 8, 2022, at 11:30 AM, Peter Relson <[email protected]> wrote: > > Joe R wrote: > <snip> > Let me use an example 00000001 00007000 000001000 00000001 00007000 00000800 > > So the allocated address is 7800 for 200 > </snip> > > Close. > > The freed storage starts at 7000 and runs for 800. > That means that allocated storage starts at 7800 and runs for 800. > > If you showed more data that preceded this, you'd have the owning TCB address. > Keep in mind that subpool 0 can be shared across tasks. > The owning task might not be "yours" or a subtask of "yours". > > <snip> > So for example I could get a block descriptor 00000001 7FFFFF88 00001000 > 00000001 7FFFFFF88 00000500 now 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 > </snip> > > This clearly is not real data from the VSMLIST that has been shown.
