Before you begin: Because MVS™ Message Service does not support translating messages to the MVS operator console, you must set up a TSO/E console that mirrors the operator's console in order to see the translated messages. TSO/E displays Japanese and Simplified Chinese messages to DBCS terminals only.

Perform the following steps to activate the MVS Message Service.

1. Compile the English and translated message skeletons.

   _______________________________________________________________

2. Create or update the following SYS1.PARMLIB members to initialize values for MVS Message Service:
   • MMSLSTxx
   • CNLcccxx
   • CONSOLxx to define the MMSLSTxx member in effect for the system

   _______________________________________________________________

3. Activate MVS Message Service.

   Tip: One way to activate MVS is to issue SET MMS=xx from the MVS operator console, where xx refers to the MMSLSTxx member of SYS1.PARMLIB.

When you are done, you have activated the MVS Message Service; translated messages will be displayed.
