CODE-SYSTEM - This configuration variable tells the runtime if double-byte character data is being accepted or displayed and which code system is being used. The possible values for this variable are:
BIG5 Taiwan code system DBC Generic Double-byte Coding scheme EUC Extended UNIX Code GB People's Republic of China code system KSC Korean code system SJC Shift JIS (Japanese Industrial Standard) Code 0 (the default) single-byte characters, either ASCII or EBCDIC
Setting CODE-SYSTEM to the proper value will allow your COBOL applications to handle input and display of Asian character data without source program changes. See also the DOS-OUTPUT-METHOD variable.
