When you specify a graphic field for the INCCHAR parameter, you should enclose the DBCS data in shift-out and shift-in characters. The command assumes that the data is in the associated DBCS CCSID of the job CCSID.
There must be a valid conversion to the field
CCSID; otherwise, an error occurs. The shift-out and shift-in characters are
removed before doing the comparison. The position specifies the DBCS character
position in which to begin the comparison.
