     <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.
