I used to work with both VM and MVS back in the 90s. Our VM guy at P&H
Mining went back to programming, so I volunteered to learn VM. We were
running VM on our 3081 with VM 4.3 running HPO. We had a whole bunch of
things people did with Cadam drawings that they had written CMS execs for.
We finally moved VM to its own box, a 4381 at the time. We were able to get
rid of it in early 1999, so we didn't have to worry about Y2K for any of its
applications.
I'm curious. The last release of VM I really worked with was 5.1 - no XP or
later stuff. Has it changed much, or are most of the concepts still the
same?

That is your experience, which is what you are writing about. I will
say it is much more rare these days than it was 20 years ago. At least
in the Chicago area. There used to be a lot of shops running VM along
with MVS (and hence many sysprogs with experience in both) but many
of them got rid of VM. The last full time VM I supported was VM/XA but
I also worked with VM/ESA and VM/HPO not long after that but there
was a full time VM sysprog that really supported those environments when I
worked on them.
It wasn't until zLinux popped up that I started working with VM again,
which
I think is getting more and more common, so the dual skill set is making
a come back.
