I have used two IBM mainframe operating systems: TSO and CMS.
A friend of mine mentioned that at her computer installation
they were changing over to MVS as the new operating system.
Not being very knowledgable about these things, I was wondering
what is the deal with that OS and whether it is something that
replaces CMS or runs under it.  Could someone give me a very
quick explanation?  I would really appreciate it.

Thanks.  RF
