Purpose

Using the MODIFY SUPP (suppression) command, you can change the message suppression level after VTAM® has been started.

Some error messages, such as those indicating abnormal termination of a task, are classified as "insuppressible" and cannot be suppressed. Other messages that cannot be suppressed include those requiring a response from the VTAM operator (messages that end in "A") and those resulting from the operator's status inquiries (messages resulting from a DISPLAY command). See z/OS Communications Server: SNA Messages for a definition of these message categories and the classifications of specific VTAM messages.

If the PPOLOG option is in effect, messages that are suppressed by the MODIFY SUPP command or the SUPP start option are still sent to the primary program operator, even though those messages do not appear on the system console.

Also see z/OS Communications Server: SNA Messages for information about message flooding.
Note:
  1. Issuing a MODIFY SUPP command prevents specific messages from being issued by VTAM. Before issuing the command, make sure that you understand the potential effects on Tivoli® NetView® for z/OS® command lists and any automated operation facilities in your network.
  2. Message suppression might prevent message IST223I (indicating the completion of the MODIFY SUPP command) from being issued by VTAM.
  3. You can use the MODIFY VTAMOPTS command (SUPP operand) to perform the same function as this command.

Operands

procname
The procedure name for the command. If procname in the START command was specified as startname.ident, where startname is the VTAM start procedure and ident is the optional identifier, either startname.ident or ident can be specified for procname.

If procname in the START command was startname, startname must be specified for procname.

SUPP
Specifies the suppression level for VTAM messages. The following list shows suppression level in the order of severity from least to most.
SUPP=NOSUP
Specifies that no VTAM messages are to be suppressed.
SUPP=INFO
Specifies that only those VTAM messages classified as informational messages are to be suppressed.
SUPP=WARN
Specifies that those VTAM messages classified as warning messages and informational messages are to be suppressed.
SUPP=NORM
Specifies that those VTAM messages classified as normal messages, warning messages, and informational messages are to be suppressed.
SUPP=SER
Specifies that those VTAM messages classified as serious error messages, normal messages, warning messages, and informational messages are to be suppressed.
