Deinstalls a page or swap file. Requires CMKRNL privilege.
  Any file installed with the SYSGEN INSTALL command can be
  deinstalled.

  If the specified file is being actively used by processes,
  this command simply marks the file as "deinstall pending".
  This prevents any new assignments or reservations to the
  file from occuring. When all outstanding references to the
  file have been removed, the deinstallation will complete.

  Files in the "deinstall pending" state are identified in the
  SHOW MEMORY/FILES display.

  Format:

   DEINSTALL file-spec /[PAGEFILE] [SWAPFILE]
            or
   DEINSTALL/ALL
            or
   DEINSTALL/INDEX=n

  Example:

   DEINSTALL DRA1:[SYSEXE]PAGEFILE.SYS /PAGEFILE
