Well, I will have to see what our ISV dump debugging product is capable of when (or if . . .) we move into EntCobol 6.3, where 64-bit is being introduced to COBOL programs for the first time. Of course, that move itself is another rotten can of worms entirely, not for this discussion.
I'm not sanguine that this particular dump debugging vendor will meet our needs, but it remains to be seen. Maybe by the time we need 64-bit support this vendor will have caught up, or maybe by that time IBM will have finally understood how bad a mistake its XPLINK direction for 64-bit code really is and engineer something far easier to use and to integrate easily into non-ISV customer development and production support environments, but I'm not hopeful in either case. I suspect that in many cases of such restrictions some ancient historical decision (justified or not) is what determined the restriction, the decision makers have long departed the company, and no one has looked at the restrictions since. ObSchiller indeed. Thanks for the reference, and how very true.

All dangerous facilities of IPCS are controlled by SAF. If your management capriciously prohibits you from using it, the responsibility is theirs. It's certainly their prerogative to ban, e.g., IEFBR14, but no outside company is obligated to rescue them from the consequences of their decision. Not all companies take essential tools away from their application developers. -- Shmuel (Seymour J.)

I haven't touched TSO TEST in umpty-ump decades and probably wouldn't use it even if offered the opportunity. In my experience it was a real bear to use, especially compared to z/XDC today. FWIW, I had to debug a quite complex assembler / BTAM / multitasking application running under the MVS of the day using only TSO TEST at a client site in another country. Got the job done, but definitely not an experience I ever wish to repeat.

IPCS? ISV products? <snip> Yes. An ESTAE(X), IEATDUMP to dump the storage from the ESTAE(X) exit, and IPCS to analyze it. We have been doing that for our non-APF authorized application that runs AMODE(64) since z/OS V1R12. z/XDC or TSO/E TEST command for interactive debugging.
