<snip> My recollection is that catching '10'X and '11'X was only for ESPIE and was intended for use by IBM. One plausible use that comes to mind is guard pages for segmented stacks. </snip>
I don't think they had such things when those ESPIE options were made available, although perhaps the concepts had been implemented. It is true that those options could only be set by authorized programs (and the ESPIE itself would still apply only to problem state). <snip> I meant "ABEND" in the sense I hear it usually used: to abnormally end, to blow up </snip> I'm sure many don't want their programs to end abnormally. I had asked because that's an argument for having recovery, not an argument for (E)SPIE vs (E)STAE(X).
