There was no "OS/MVT", and Shirley OS/360 Release 15 was worse than
Release 19; IBM wound up shipping a Release 15/16 to follow Release
14.

TSO had nothing to do with C/R. Perhaps you're thinking of
Rollin/Rollout, but AFAIK TSO didn't use any of that code.

TSO swap support worked the same regardless of the command running.

No, owned by the TIOC.

No; The Terminal Monitor Program (TMP) has nothing to do with either
the TCAM DCB or the Region Control Task (RCT).
>In other words, *all* TSO users shared *one* (1) MVT region
No; you could have up to 15 TSO regions if storage allowed.
>The same concept was integrated subsequently into OS/VS1
No, only OS/VS2. For OS/VS1 you were stuck with CRJE.
