Position 44 is used to specify edit codes that suppress leading zeros in a numeric field or to punctuate a numeric field without using an edit word. Allowable entries are 1 through 9, A through D, J through Q, X, Y, Z, and blank.
For more information on edit codes see Chapter 10. Editing Numeric Fields.
Edit codes 5 through 9 are user-defined edit codes and are defined externally by an IBM i function. The edit code is determined at compilation time. Subsequent changes to a user-defined edit code will not affect the editing by the RPG IV compiler unless the program is recompiled.
