VMS was ( I’m using the past tense because I haven’t worked with it for 7 years ) actually a GREAT operating system.
Robust and easier to use and understand than UNIX.
Last I heard, Hewlett Packard owns the OS.
I wonder how many companies are still using it...
I was working for a company that was MIGRATING AWAY from it.
VMS has been all but dropped so without support people are migrating. It served it purpose in many software houses and did very well. I always thought if it weren’t for UNIX being free, VMS would have dominated for years to come.
