  Control Message Levels

Purpose:  Use the CONTROL V,LEVEL command to specify the message levels for messages that are to be displayed at a console. The LEVEL parameter on the CONSOLE statement in the CONSOLxx member of SYS1.PARMLIB controls the message levels for the console at IPL. If the LEVEL parameter is not coded, the system sends all messages, including broadcast messages, to the console.

 K V[,REF ]                 [,L={cc  }]
    |                          {name}
    |,LEVEL=(type[,type]...)

Parameters

V,LEVEL=(type[,type]...)

The message levels for a console are to be changed. The following operands specify which messages are to be displayed at the console. You can enter more than one of the following operands. If you do, place parentheses around the list of operands and separate them with commas. type can be any of the following:

ALL The system is to display messages routed to the console including broadcast messages. When a console is initialized, the ALL option is in effect.

CE Critical eventual action messages (descriptor code 11) are to be displayed

E Eventual action messages (descriptor code 3) are to be displayed

I Immediate action messages (descriptor codes 1 and 2) are to be displayed

IN Informational messages are to be displayed

NB Broadcast messages are not to be displayed.

R Write-to-operator with reply (WTOR) messages are to be displayed.

UNCOND The system is to execute this command even though it means broadcast and informational messages with certain routing codes will not be assigned to any console. Use this operand if you want broadcast and certain informational messages to be sent only to the hardcopy medium.

Notes:

  1. If an informational message is not directed to any console, it is routed to the system log.

  2. If you donít specify NB, your console receives broadcast messages.

  3. If a WTOR or action message is not directed to any console, it is routed to the consoles with the UD attribute.

  4. If a message is directed to a specific console, it appears there regardless of the message level of the console.

  5. If you specify a second K V,LEVEL command, the K V,LEVEL command in effect is cancelled.

  6. If you specify only one message type on the LEVEL operand, you can omit the parentheses.

REF

Displays the current value of the CONTROL V,LEVEL operand.

L=cc or name

The console where the specified action is to take place. The issuing console is the default. An operator at one full-capability console cannot change the message level of another full-capability console.

Example 1

To route only informational and broadcast messages to console CON20, enter:

K V,LEVEL=IN,L=CON20

Example 2

To route WTOR, immediate action, and broadcast messages to the issuing console, enter:

K V,LEVEL=(R,I)

Example 3

To route all messages except broadcast messages to the issuing console, enter: 

K V,LEVEL=(ALL,NB)

Example 4

To suppress all broadcast and informational messages destined for the issuing console, enter:

K V,LEVEL=(NB,UNCOND)

This example is of special interest to those installations that use consoles to print tape labels. Here, broadcast messages and informational messages with certain routing codes will be sent directly to the hardcopy medium without appearing at the issuing console. If your consoles are set up so that informational messages with certain routing codes or broadcast messages are not sent to a console, the system executes the command and sends you a warning message. It then issues message IEE250I to inform you of the message loss at your consoles.
