You can set up a default language for all users of the z/OS shell. You can also customize your system so that z/OS UNIX messages are displayed in Japanese or Simplified Chinese. (They are available in English, Japanese, or Simplified Chinese.)

• For the z/OS shell, if you want to set the language for yourself, or for just one user, you can make these changes in the $HOME/.profile, or log on to the z/OS shell and export the LANG and NLSPATH environment variables.
• For the tcsh shell, if you want to set the language for yourself, or for just one user, you can make these changes in the $HOME/.login, or log on to the z/OS shell and set the LANG and NLSPATH environment variables.
