Having had a couple of replies re my discussion of IBM OS/VS etymology...
   MFT (Multiprogramming, Fixed number of Tasks) became OS/VS1 and stayed.
   MVT ("                 Variable...) became OS/VS2, and then...
   ...thru release 1.highest, used only a _single_ problem-state address
      space and was thus known as SVS (Single Virtual Storage);
   ...with release 2.0 and later, used (supposedly) _multiple_ problem-
      state address spaces and was thus known as MVS (Multiple...).
Sokay?
Regardz,
