Could you please share the code Z/OS uses to execute authorised programs? </snip> I'm afraid that what you think you know in this regard is incorrect. Maybe it was true decades ago but has not been true in the recent decades. I don't recall much discussion about RSAPF over the years; the results would have been the same then as now. The authorization of a jobstep (as represented by JSCBAUTH) is determined when the jobstep starts (based on the simple rules that likely all in this discussion know - the authorization of the concatenation/data set from which the jobstep program is fetched and the AC(1) option). That authorization can be decreased. It can never be increased (including after it has been decreased). For those who wonder about TSO/E, the necessary (but not in and of itself sufficient) point is that TSO/E has an "authorized side" and an "unauthorized side" and while executing a program on the "authorized size" literally nothing can run on the unauthorized side (which has been set non-dispatchable) This is not something that should be done by any program other than the OS itself for extremely specific circumstances. So IBM must say "no" to the question asked.
