Hmm.  It tells me three things.
(1) IBM didn't think of using functional or mostly-functional languages in MVT.
(2) IBM had a habit of dropping support for their operating systems (there
    were several /360 operating systems; it made business sense for IBM to
    concentrate on just a few).
(3) Without knowing what _else_ was different between MVT and MVS, no
    conclusions can be drawn.

I thought CICS put everything in one address space.
Does it/did it?
