Since OCESQL4J ignore GRP. in the above program, the generated COBOL code is invalid because of a collision of variable names.

OCESQL     CALL "OCESQLSetSQLParams" USING
OCESQL          BY VALUE 16
OCESQL          BY VALUE 1
OCESQL          BY VALUE 0
OCESQL          BY REFERENCE ITEM
OCESQL     END-CALL
