Cause . . . . . : A subfield is defined with graphic data type but the length as specified by the From-Position and To-Position entries is an odd number. Since one DBCS character takes up two bytes, the length of a graphic field must be an even number.
Recovery . . . : Change the From-Position or To-Position entry so that the length of the subfield is an even number. Compile again.
