As consequence of not being able to fix TSO &/or MVS, POK had a project to port CMS to MVS ... as a way of providing interactive services, but as mentioned previously MVS has some fundamental flaws for providing interactive service ... and the implementation never really caught on.
Lynn: I'm quite familiar with that project. Three others and I actually implemented a prototype which let a TSO user issue the command CMS which would obtain a block of storage in the TSO address space and load and run the CMS kernel using SIE. Attempts to perform file I/O would interrupt SIE and execute code which implemented the CMS file system and all needed file functions in a VSAM data set, using CI file I/O. A later design would use the VSAM actual block processor, as opposed to CI file I/O. That file system implementation was my contribution to the project. Two of us were assigned as technical team leaders for the intended product development. We were staffing our teams when the project was killed.
