Displays the message classes that are currently affected by the
    SET BROADCAST command.

    Format

      SHOW BROADCAST

1  –  Qualifier

1.1    /OUTPUT

       /OUTPUT[=filespec]
       /NOOUTPUT

    Controls where the output of the command is sent. If you do
    not enter the qualifier, or if you enter the /OUTPUT qualifier
    without a file specification, the output is sent to the current
    process default output stream or device, identified by the
    logical name SYS$OUTPUT.

    If you enter the /OUTPUT qualifier with a partial file
    specification (for example, specifying only a directory), SHOW
    is the default file name and .LIS is the default file type. The
    asterisk (*)  and the percent sign (%) wildcard characters are
    not allowed.

    If you enter the /NOOUTPUT qualifier, output is suppressed.

2  –  Examples

    1.$ SET BROADCAST=ALL
      $ SET TERMINAL/NOBROADCAST
      $ SHOW BROADCAST
      Broadcasts are enabled for all classes
      Terminal is set "No Broadcast", no broadcast messages
      will be displayed.

      The display in this example shows that all message classes
      are enabled for broadcast, but that these messages will not be
      received because the terminal is set NO BROADCAST.

    2.$ SHOW BROADCAST
      Broadcasts are currently disabled for:
          MAIL

      The SHOW BROADCAST display in this example indicates that SET
      BROADCAST=NOMAIL is in effect.

    3.$ SET BROADCAST=(NOALL,USER1)
      $ SET TERMINAL/NOBROADCAST
      $ SHOW BROADCAST
      Broadcasts are currently disabled for:
          GENERAL
          PHONE

      are enabled, but will not be received, because the terminal is
      set NO BROADCAST.
