What can I do with this system value?
This system value specifies whether the DBCS version of the system is installed. 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 DBCS.
For example, languages that are based on ideographic characters, such as Japanese, Chinese, and Korean, require double-byte character sets.
For IBM i V5R3, or later, double-byte capability is always installed. For OS/400® V5R2, or earlier, you must install one of the DBCS versions of IBM i 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.
