   /[NO]SINGLE_WINDOW

   Determines whether an MS Server process or individual MultiSessions
   NDC-terminal windows will be watched.

   The default for a PEEK, SPY or WATCH command is determined by the
   logical WATCHER$BACKGROUND usually defined by PEEK_DEFAULTS.COM. You
   can override the default by using this command qualifier.

   Note that the default behavior without /SINGLE_WINDOW is to see the
   screen of the MS Server process, whether or not wildcards are used.

   Examples:

   $ PEEK/TERM=-NDC21 /SINGLE_WINDOW ! Watch terminal NDC21:
   $ PEEK/TERM=NDC* /SINGLE_WINDOW   ! Watch all NDC terminals.
   $ PEEK * /NOSINGLE_WINDOW         ! Only watch MS Servers, don't
                                     ! watch any NDC terminals.
