Edward:
I can say something about that, as I was a member of the team that
developed the prototype and was scheduled to become the leader of one of
the two development teams charged with the planned "CMS on MVS" product.
While we were getting staffed up, IBM canceled the project. The planned
team leader for the other development team, who was also a member of the
prototype team, was the late Karl Finkemeyer, who had created a PR/SM
prototype he called "The Thin Layer" while working at the Heidelberg
Scientific Center.
We had successfully IPLed and run CMS in a TSO address space using SIE.
The CMS nucleus was unmodified. Our prototype was proof of the
feasibility of the product. There was no VM in our prototype, though we
had to implement some underlying functionality. My part in the prototype
was the implementation of the CMS file system, which I did using Control
Interval access in a VSAM data set. I believe that the idea was later
used as a basis for PDS/E and HFS, although by the time both of these
came along, I had left IBM and gone into consulting

Back in the days. There was CMS for MVS in the early 80's. One of the
developers was a regular at SHARE and I guess resigned due to the decision to
shelve it for 'Marketing Considerations'. Went on the shelf right next to the
Clist Compiler-CLIC.

Would not the proper phrase be "run independently of CP"? CMS is a
component
of z/VM; it can't be independent of z/VM, it *is* z/VM.
