If you have the SPECIAL attribute, you can specify the installation defaults for national languages on your system. You can specify a primary language and a secondary language. Applications that use the RACROUTE REQUEST=EXTRACT request to determine a user's primary and secondary languages can use the installation defaults set by SETROPTS if the user does not have his or her own language preferences.

SETROPTS LANGUAGE(PRIMARY(language1) SECONDARY(language2))

You must specify a 3-character language code unless RACF® is running with the MVS™ message service active.

LANGUAGE(PRIMARY(ENU) (SECONDARY(ENU)), which means American English, is in effect when a RACF database is first initialized using IRRMIN00.
