General Information

The SUPPRESS subparameter allows suppression of messages that do not require operator intervention from the console and from the SYSLOG. This subparameter can also be used for operator command security – authorizing certain commands for certain environments.

Descriptor codes determine message display characteristics such as deletion, scrolling, highlighting or color. For additional information regarding routing and descriptor codes, refer to the IBM publication Routing and Descriptor Codes, GC38-1102.

The NEWTEXT subparameter permits modification of the text of a message, or command syntax, before it appears on the console. It is used, for example, to make a message more meaningful, to standardize installation messages, or to translate messages from English to another language. NEWTEXT also supports Control-O AutoEdit variables. AutoEdit symbols embedded in NEWTEXT are dynamically edited at time of rule activation. This permits, for example, inclusion of data contained in the nth word of a message, or the job ID of the job issuing the message, or the reply ID from a reply question. For more information about the AutoEdit facility, see AutoEdit Facility.

The ROUTE subparameter permits rerouting of messages to any number of consoles, using multiple DO DISPLAY statements.

Suppressing a command's execution.

In addition to suppressing the command's echo message (the message that logs the command) the command will be suppressed from execution if the following conditions are true:

1. For JES2 commands, the PARAMETER JCMDSSN in CTOPARM is not NO.
2. For other subsystems that can receive operator commands, the IOA subsystem must be defined in the subsystem list (IEFSSNxx) before the receiving subsystem is defined in the subsystem list.
