Modifying message module identification

You can choose to include in VTAM® messages the last 5 characters of the VTAM module that issued the message. The module name abbreviation is displayed between the message ID and the message text.

To insert or delete module name abbreviations, use one of the following methods, where YES indicates to insert the abbreviations and NO indicates to not include them:

Specify MSGMOD=YES|NO in the start option
Issue the F net,MSGMOD=YES|NO command
Issue the F net,VTAMOPTS,MSGMOD=YES|NO command

MSGMOD=NO is the default value. For more information about the MODIFY MSGMOD and MODIFY VTAMOPTS commands, see z/OS Communications Server: SNA Operation.

Examples:

If you specify MSGMOD=YES, VTAM message xxxxx, where xxxxx is an operating system unique message number, is displayed as:
```
xxxxx   INFXI   DUMP OF ncpname COMPLETE
```
If you specify MSGMOD=NO, the message is displayed as:
```
xxxxx   DUMP OF ncpname COMPLETE
```

Note:

Any message that exceeds the maximum message length after the insertion of the module ID is truncated.
If your installation has changed the message text and omitted the message ID, the module name is the first item in the message.
