The MVS™ message service (MMS) enables your installation to use message files to display translated messages. MMS substitutes a message translated into another language for the equivalent U.S. English message.

For TSO/E to display translated messages, your installation needs to format install message files that contain U.S. English message skeletons and the translated language message skeletons using the MVS message compiler.

For MVS messages, IBM® provides the install message file for U.S. English messages and the install message file for Japanese translations. IBM also provides TSO/E install message files in upper and mixed case U.S. English and Japanese. For language translations other than Japanese, your installation must supply its own version of the install message file with the appropriate translated message skeletons. For more information, see .
