PEEK and SPY have a "screen-saver" feature that may be used to allow
   the watcher to see the initial contents of a user's screen when watching
   begins.

   Since VMS does NOT store the screen contents, and since the VMS terminal
   driver just "throws away" output buffers when its done with them,
   normally there is no way to see what is currently on a user's screen
   when one first begins watching.

   Peek/Spy could, however, be used to take control of the user's screen
   and keyboard, and then enter a refresh-screen sequence to the active
   program to tell it to redisplay the screen's current contents.

   The drawback with this approach is that there are many VMS programs
   (including DCL and many home-grown menu systems) which do NOT have
   any screen-refresh command programmed into them, so this technique
   doesn't ALWAYS work.

   Thus for version 2.0 and upward of Peek/Spy we have added the capability
   of saving the screen contents for selected users on your system so one
   gets a full intial-screen display when one starts watching the user.

   The way this is done differs for the VAX and the ALPHA.

1  –  ALPHA

     For the ALPHA screen-saving is done as follows:

       For each user for whom you wish to save the screen contents,
       issue the following commands in his LOGIN.COM command file:

               $ PEEK :== $ PEEK$LOCATION:PEEK_V6
               $ PEEK /SAVE_SCREEN

       These same commands may be added to the SYS$MANAGER:SYLOGIN.COM
       file instead, if you wish to save the screens for everybody.

       The /SAVE_SCREEN can also take a /LOG_FILE qualifier to make
       a log file of everything that is sent to the screen. See the
       top-level PEEK Subtopic: Commands SAVE_SCREEN.

2  –  VAX

     For the VAX screen-saving is done as follows:

       A) Install MultiSessions from the same distribution tape as PEEK
          was shipped on. See the quick installation sheet for that
          product or use the following command:

               $ @SYS$UPDATE:VMSINSTAL MS MSA0:

       B) Start MultiSessions, using the following command:

               $ @SYS$SYSDEVICE:[MULTISESSIONS]MS_STARTUP

       C) For each user for whom you wish to save his screen contents,
          issue the following commands in his LOGIN.COM command file:

          $ MS*UTIL :== $ MS$LOCATION:MSUTIL_V5
            (or MSUTIL_V4 If you are using VMS version 4)
          $ MS PEEK_ONLY /OPTIONS=(BROADCAST_REFRESH,ORIG_TERM,NOSTATUS)

          These same commands may be added to the SYS$MANAGER:SYLOGIN.COM
          file instead, if you wish to save the screens for everybody.

   If a user is already using MultiSessions, these steps should be
   skipped as Peek/Spy will already be able to display his initial
   screen contents.

   Note that the PEEK_ONLY mode of starting MultiSessions does NOT allow
   the user to create extra sessions, or allow him to print his screen.
   It merely saves his screen for Peek/Spy to display when you first
   start watching his terminal. PEEK_ONLY may be issued by licensed users
   of Peek/Spy without having to receive any extra license keys for
   MultiSessions.
