   <operating system> (MVS) Release 2 of {OS/VS2}, called MVS
   because it had multiple 16 MB virtual address spaces, in
   contrast to {SVS}.  MVS ran on the {IBM 390} series
   {mainframes}.  It became MVS/SP, then MVS/XA (with 31-bit
   addressing) and then MVS/ESA.

   MVS/Open Edition (MVS/OE), aimed at the growing {open systems}
   market, added {TCP/IP} and {Unix} support in an MVS address
   space, allowing users to run IBM, {CICS}-type applications,
   {batch} applications and Unix.

   MVS/ESA was repackaged as {OS/390} as a marketing exercise but
   it's basically the same thing.

   Version: 5.1.
