$ PEEK/SAVE_SCREEN /OUTPUT_LOG_FILE [=file_spec]

   SAVE_SCREEN/OUTPUT_LOG_FILE[=file] is used to create a log file
   containing everything output to the terminal while the screen-
   saving is in effect.

   The default filespec is taken from the logical SAVE$OUTPUT_LOG_FILE.
   This logical may be defined system-wide by PEEK_DEFAULTS.COM, or it
   may be defined in any of the logical-name tables specified in
   LNM$PEEK_TABLE_SEARCH_LIST, which is defined by PEEK_DEFAULTS.COM.
   See the top-level PEEK Subtopic: Defaults.

   If this logical is not defined and if /OUTPUT_LOG_FILE is specified
   without the optional file-spec, then PEEK will generate a log file
   in the current default directory using a default log-file name of:

       PEEK_TRMLOG_username_terminalname.LOG

   If a log file is already being made, then it can be closed with a
   $ PEEK/SAVE_SCREEN/CLOSE_FILE command.

   To close the current log file and start logging to a new log file
   use a $ PEEK/SAVE_SCREEN/LOG/NEW_FILE command.

   The /REOPEN qualifier also affects PEEK/SAVE_SCREEN/LOG.

   Terminal logging with /SAVE_SCREEN/LOG is terminated by a
   PEEK/SAVE_SCREEN/CLOSE_FILE command, or a PEEK/NOSAVE_SCREEN command.

   Example:

        $ PEEK/SAVE /OUTPUT=SAVE_OUTPUT

   Note that /LOG and /OUTPUT_LOG are synonymous.
