Using a double-byte character set (DBCS)

If you want to display or enter double-byte data, you must:

Work at a terminal that is configured to generate data in code page IBM-939 and follow the procedures for the terminal emulator being used, if any.
Specify special LOGMODEs to access TSO/E and VTAM® support for DBCS. Typically the systems programmer sets them up and provides you with instructions.
Run the TSO/E PROFILE PLANGUAGE(JPN) command, if required, to receive Japanese-language messages from the OMVS interface to the shell. Do not change your PROFILE PLANGUAGE when temporarily switched to TSO/E from the shell. After you invoke the shell, OMVS will not change the language of the messages it issues until you exit the shell and return to TSO/E, change your PROFILE PLANGUAGE, and reinvoke OMVS.
Use the null translate table (the default) for character conversion. You do not need to specify the CONVERT keyword on the OCOPY, OGET, OGETX, OPUT, and OPUTX commands.
Access the shell using the OMVS command with the DBCS keyword, the default setting.
Define a single-byte escape character for typing an escape sequence, if you do not use the default ¢.

The shell utilities (for example, grep and ed) work with DBCS data in the file system and can be used to create DBCS data in the file system.
