Additional Notes on Field and Format Names

If the generated field name is a COBOL reserved word, the suffix -DDS is added to the field name. If the generated field name originates from a physical file (in other words, the field is an argument of the CONCAT or RENAME keyword), the suffix is also added. For more information, see the IBM Rational Development Studio for i: ILE COBOL Programmer's Guide.

The REPLACING phrase cannot be used to change the name of a key field or a format name when EXTERNALLY-DESCRIBED-KEY is used.
