No, that still doesn't work, Wayne, as it still has that ambiguous ues of 
"under". I think you really do need to say 'with the same TCBJSTCB" rather than 
"under a given JSTCB".

Consider, for example, the case where you have // EXEC PGM=A where A, running 
authorized, attaches B and C both as jobstep TCBs, and with separate TIOTs.

B then attaches non-jobstep TCBs B1 and B2, which share B's TIOT.

C attaches non-jobstep TCBs C1 and C2, which share C's TIOT.

In the sense of subtasking, all of B1, B2, C1, and C2 are "under" A, but none 
share A's TIOT.
