Mike sent me a test case. As I suspected, the first program check is in the prologue of the routine that traps console output in the COMMAND interface. This leads to program checks in DMSMGM undoubtedly when I try to report the program check in the pipeline code.
Running multiple CMS commands concurrently is asking for trouble; and running multiple COMMAND stages concurrently even more so, as the magic and mirrors that make it happen is in parts of CMS that is not re-entrant. Like, would you contemplate running two HLASMs concurrently? Or COPYFILE? Or just about any CMS command? Most of them are not re-entrant. I shall update the preface accordingly. j.
