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.
Customize your locale and use the chcp command to specify the ASCII and EBCDIC code pages you are using.
- For information on how to customize your locale and configure your setup files, see Changing the locale in the shell for the z/OS® shell, or Changing the locale in the shell for the tcsh shell.

When you are working with a double-byte character set, there are some restrictions. See Single-byte restrictions for more information.
