Each graphic string is further defined as one of:
Every DBCS graphic string has a CCSID that identifies a double-byte coded character set. If necessary, a DBCS graphic string is converted before it is used in an operation with a DBCS graphic string that has a different DBCS CCSID.
When graphic-string variables are not explicitly tagged with a CCSID, the associated DBCS CCSID for the job CCSID is used. If no associated DBCS CCSID exists, the variable is tagged with 65535. A graphic-string variable is never implicitly tagged with a UTF-16 or UCS-2 CCSID. See the DECLARE VARIABLE statement for information on how to tag a graphic variable with a CCSID.
