Graphic compile-time data can only be specified when the source CCSID supports double-byte characters.

Cause . . . . . : Graphic compile-time data can only be coded in a source file whose CCSID is a mixed CCSID that supports both single-byte and double-byte characters. If the Graphic compile-time data is in a /COPY file with a mixed CCSID, the primary source file for the compilation must also have a mixed CCSID. The compiler enforces this rule only when CCSID(*EXACT) is specified.
Recovery . . . : Correct the CCSID of the source file containing the Graphic compile-time data, or correct the CCSID of the primary source file. Compile again.
