Displays a message at a system operator's terminal and optionally
   requests a reply. All messages are logged at the operator's
   console and in the operator's log file, if that file is
   initialized.

   To use this command, you must start the operator communication
   process (OPCOM) at boot time by specifying the DCL command
   @SYS$SYSTEM:STARTUP OPCOM in the site-specific startup command
   file, SYS$MANAGER:SYSTARTUP.COM.

Examples

   characters, or lowercase characters, enclose it in quotation marks
   (" ").

Additional information available:

/REPLY/TO

   Requests a reply to the message and issues a unique identification
   number to which the operator sends the response. The system
   displays a message that the operator has been notified; you
   cannot enter any commands until the operator responds. If you
   press Ctrl/C before the operator responds, you can then enter
   another message to the operator, or press Ctrl/Z to cancel the
   request.

      /TO=(operator[,...])

   Specifies one or more operators to whom you want to send the
   message. Possible keywords are as follows:

   CARDS                 Sends the message to operators designated to
                         respond to card reader requests.

   CENTRAL               Sends the message to the central system
                         operator.

   CLUSTER               Sends the message to operators designated to
                         respond to cluster-related requests.

   DEVICES               Sends the message to operators who mount and
                         dismount disks.

   DISKS                 Sends the message to operators who mount and
                         dismount disk volumes.

   NETWORK               Sends the message to the network operator.

   OPER1 to OPER12       Sends the message to operators identified as
                         OPER1 to OPER12.

   PRINTER               Sends the message to operators designated to
                         handle print requests.

   SECURITY              Sends the message to operators designated to
                         respond to security-related requests.

   TAPES                 Sends the message to operators designated to
                         mount and dismount tape volumes.

   1.  $ PRINT/COPIES=2/QUEUE=LQ_PRINT  REPORT.OUT/FORM=LETTER
         Job REPRT (queue LQA1, entry 401) pending
       $ REQUEST/REPLY/TO=PRINTER -
       _$"Have queued job 401 as FORM=LETTER;  can you print it?"
       %OPCOM-S-OPRNOTIF, operator notified, waiting...10:42:16.10
       %OPCOM-S-OPREPLY, AFTER 11:00
        19-APR-1990 10:25:32.40, request 3 completed by operator OPA0

     In this example the PRINT command requests that multiple copies
     of a file be printed using a special paper (/FORM=LETTER).
     After queueing the job to the printer, the REQUEST command
     sends a message to the system operator.

     The operator sends a reply after completing the request.

   2.  $ REQUEST/REPLY  "Are you there?"
       %OPCOM-S-OPRNOTIF, operator notified, waiting...14:54:30.33
<Ctrl/C>

       REQUEST-Enter message or cancel request with ^Z
       REQUEST-Message?<Ctrl/Z>
       %OPCOM-S-OPRNOTIF, operator notified, waiting... 14:59:01.38
       %OPCOM-F-RQSTCAN, request was canceled

     In this example the REQUEST command issues a message and
     requests a response. When no operator replies to the question,
     Ctrl/C is used to interrupt the request; then Ctrl/Z is used to
     cancel it.
