>I'm basing everything I'm doing on the Principles of Operations manual >(POM). The Z/Architecture is the final authority for any program even MVS.
An interesting opinion. But I'd say "not overly relevant". Sure, you can consider the Principles of Operation to be the final authority for what the machine does. That document does not in any way define what the operating system supports. And when you do something not supported by the operating system, it is your risk to bear, if the operating system has chosen not to enforce other than by documentation (even lack of "we support it" documentation). Suppose, for example, you use "Wait" via SVC from an RMODE 64 routine. You might get into Wait just fine (although at this point the SVC FLIH would reject it, I believe, except for the abend SVC). But Wait does stuff based on the invoker's address and Wait is not cognizant of an address above 2G. There are other more subtle things that could come into play even for a PC-entered service that are related to the caller's address. You are betting that none of them happen or come into play, without having much way of validating if that is or is not true. Those might be functional things, or diagnostic things.
