>>-+--------------------------------+-------------------------->< '-DESC--=--(--descriptor_code--)-'
| macroinstructions: | USSMSG |
| dependencies: | VTAM® operator messages only |
Specifies the descriptor code to be used for this message. This operand is coded exactly like, and has the same meaning as, the DESC operand of the WTO or WTOR macroinstruction. For information about how to code this operand, see z/OS MVS Programming: Authorized Assembler Services Reference SET-WTO.
This operand applies only to messages that are sent to the VTAM operator. VTAM ignores this operand when sending a message to a program operator.
If the DESC operand is omitted or is specified with a null value (DESC=), VTAM uses the DESC value specified for this message ID in the next USS table searched.
