RTCDSDPL in IHARTCT can indicate whether or not a dump is in progress. The RTCTSDF3 array indicates which ASIDs are involved. Caveat emptor, as these fields are not designated as programming interfaces.

However, code running under a different work unit (such as the SRBs and PCs from work units in other address spaces which were previously mentioned in this discussion) may find it challenging to serialize against the termination of the selected TCB. And, TCBNDSVC is not designated as a programming interface. > Why are so many OS/VS1 symbols still in there? That was before my time (in MVS development). I might guess reasons like: 1. To allow old programs to continue to be assembled. 2. To remind us in development to not reuse fields when that might break old programs. Jim Mulder z/OS System Test IBM Corp.
