<snip> I am looking at some SMF 30 S222 ABEND completion codes. Most of them are S222-0000 as you would expect A handful have a non-zero reason code, many of them A618. </snip> What exactly are you "looking at"? Are you referring to something formatted from fields SMF30SCC and SMF30ARC?
<snip> The ABEND 222 documentation does not mention reason codes </snip> That's because the system completion code 222 (it is not "ABEND 222" if you want to be picky) that you get from a cancel does not have a reason code. It comes from CALLRTM TYPE=ABTERM,COMPCOD=(5),TCB=(11),DUMP=NO,STEP=YES (or the same with DUMP=YES). The reason is not x'A618' (or 0 for that matter). There is no reason code. Some messages do not differentiate that fine point, such as IEF472I RUNJOB TC1 - COMPLETION CODE - SYSTEM=222 USER=0000 REASON=00000000 which (presumably for simplicity) uses the value from TCBARC to show REASON=xxxxxxxx even when there is no reason code. In this case, TCBARC is 0. There is a bit indicating if the reason code in TCBARC is valid. That's (ridiculously-named) bit TCBRV316 which would be 0. A "better" name will likely be added in the future. SMF30ARC, similarly, is set unconditionally from TCBARC. I don't see anything indicating that SMF 30 captures the "validity bit". I have a (vague, possibly faulty) recollection of being disturbed at finding something issuing an abend with system completion code x'222' as if that was a cancel and as if it was OK to do so (in general, it is not, but it would have been that way for a long time and been somewhat incompatible to change). Such an abend might have some sort of reason code -- and of course should be documented -- if indeed that is the case. A x'222' system abend (as opposed to a x'222' abterm) is not a true cancel and might not be treated as such.
