The DBCS system indicator (QIGC) is used to specify whether a double-byte character set (DBCS) national language version is installed. This value is set when the primary national language version is installed.
If QIGC is set to 0, no DBCS national language version is installed on the system. When QIGC is set to 0, the coded character set system identifier (QCCSID) must be set to an SBCS coded character set identifier.
If QIGC is set to 1, a DBCS national language version is installed as the primary language on the system. When QIGC is set to 1, the coded character set system identifier (QCCSID) system value should be set to a mixed CCSID (such as 05026) or to CCSID 65535.
You cannot change this value.
