The character identifier (QCHRID) is used to specify the character set and code page CHRID(*SYSVAL) for the CL commands that create, change, or override display files, display device descriptions, user interface (UIM) menus, panel groups, and printer files.
You can change this value if the system QCCSID system value is set to CCSID 65535. You can also change the QCHRID value if the code page portion of the new QCHRID value is the same as the code page portion of the QCCSID value.
