What can I do with this system value?

Specifies whether the double-byte coded character (DBCS) version of the system is installed (1) or not (0). A DBCS is a character set in which each character is represented internally by a 2-byte code point. Languages that contain more characters than can be represented internally by 256 code points require double-byte coded character sets.

For example, languages that are based on ideographic characters, such as Japanese, Chinese, and Korean, require double-byte character sets.

For i5/OS V5R3 or later, double-byte capability is always installed. For i5/OS V5R2 or earlier, you must install one of the DBCS versions of i5/OS to support Japanese, Chinese, or Korean.

This value is not editable; it is set by the system. You can refer to this system value in an application program.
