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 Richard T. Ferris ferris@eniac.seas.upenn.edu University of Pennsylvania
