SUPP

Specifies the message suppression class to be used for this message. The message suppression class for a message, along with the SUPP start option and the MODIFY SUPP command, determines whether a particular message will be suppressed by VTAM®.

If the SUPP operand is omitted or is specified with a null value (SUPP=), VTAM uses the SUPP value specified for this message ID in the next USS table searched.

You cannot suppress individual VTAM messages in a multi-line WTO (MLWTO) message (that is, messages identified as issued as part of a message group). You can suppress message groups by suppressing the message identified as the first in the group. See z/OS Communications Server: SNA Messages to identify messages issued as part of a group.
