Bernd O wrote <snip> I'd suggest to be very careful with such codings; a co-worker some years ago did this and - by accident - the code ran privileged, which caused the whole LPAR to hang.
Same goes for ST at address zero, which was suggested by another poster. </snip> I challenge both of those. The first will never happen unless something changed to key 0 (being privileged is relevant only to the extent that you could then change to key 0). And that doesn't happen without intent. The second will never happen outside of the OS itself in the absence of an APARable z/OS error (related to what we refer to as low-core protect).
