VAXTPU SET(BELL) — VMS 5.2

 SET(BELL)

 Enables or disables the terminal bell for messages (all or only
 broadcasts).

 Syntax

    SET (BELL, {ALL | BROADCAST}, {OFF | ON})

 Parameters

    ALL        Specifies that ON or OFF applies to all messages.

    BROADCAST  Specifies that ON or OFF applies only to broadcast messages,
               such as from MAIL or REPLY.

    OFF        Disables the bell for ALL or BROADCAST messages.

    ON         Enables the bell for ALL or BROADCAST messages.

 Comments

 A bell character (ASCII decimal 7) in message text does not cause the bell
 to ring; VAXTPU displays bell characters as uninterpreted control codes.
 You can also use DCL commands to affect the display of broadcast messages
 within VAXTPU.  If you use the DCL command SET TERMINAL/NOBROADCAST, no
 broadcast messages are sent to your terminal.  Also, using the DCL command
 SET BROADCAST controls some kinds of broadcast messages.

 Example

 The following procedure saves the existing bell state, turns it on for
 messages, outputs a message with a bell, and then restores the previous
 bell state:

    PROCEDURE user_ring_bell (msg_string)
       local bell_state;
       bell_state := GET_INFO (SYSTEM, "bell");
       SET (BELL, ALL, ON);
       MESSAGE (msg_string);
       IF bell_state = 0
          THEN
             SET (BELL, ALL, OFF);
          ELSE
             IF bell_state = BROADCAST
                THEN
                   SET (BELL, BROADCAST, ON);
             ENDIF;
       ENDIF;
    ENDPROCEDURE;
