The MVS™ message service (MMS) enables your installation to use message files for message translation. MMS substitutes a message translated into a different language for the U. S. English equivalent message. If MMS is active, authorized users of extended MCS consoles on TSO/E can select available languages for message translation and receive translated messages on their screens. Application programs can also use MMS to handle translation of messages. Depending on how the installation displays the messages, users can receive those translated messages wherever they are displayed or recorded.
TSO/E terminal users can also receive translated messages (including TSO/E messages) during a TSO/E session or from a batch job.
For MMS to handle translated messages, your installation must use the MVS message compiler to format install message files that contain English message skeletons and the translated language message skeletons.
IBM® provides English and Japanese versions of MVS messages and English and Japanese versions of TSO/E messages. If you want languages other than Japanese, the installation must supply its own version of the translated message skeletons.
Applications can use macros for the MVS message translation services. For information on how applications handle message translation or how to create message skeletons for languages, see z/OS MVS Programming: Assembler Services Guide.
