Library /sys$common/syshlp/patchhelp.hlb CANCEL, PATCH_AREA  *Conan The Librarian (sorry for the slow response - running on an old VAX)

      Use CANCEL PATCH_AREA to reset the  current  patch  area  from  a
      user-defined  patch  area  to  the default patch area.  Any patch
      space needed thereafter will be taken from the default patch area
      until the next SET PATCH_AREA command is issued.

      The CANCEL PATCH_AREA command is used  primarily  when  you  have
      issued  the  SET  PATCH_AREA  command to establish a user-defined
      patch area as the current patch area.  After  you  have  inserted
      the  necessary  patch  information  into  that  area, type CANCEL
      PATCH_AREA to resume use of the default patch area.

 Format:
