At the end of task termination, we free the storage containing the TCB/STCB under which we are running, and set PSATOLD to the address of the WAIT TCB (which is in the nucleus). That gets traced in some SSRV 78 entries for some more FREEMAINs, and then we enter the dispatcher. Jim Mulder z/OS Diagnosis, Design, Development, Test IBM Corp.
