The IGCCDEFNT parameter is used when generating Advanced Function Presentation data stream. If the data stream contains double-byte data (IGCDTA(*YES)), a font substitution to the DBCS coded font takes place.
In an externally described file (DDS), the user can use the IGCCDEFNT DDS keyword to specify a DBCS font. This font will be used to print any DBCS data encountered in that field or record. If the user has a DBCS-graphic field specified, the printer file IGCCDEFNT parameter is used unless the IGCCDEFNT DDS keyword has been specified at the record or field level.
