The syntax is as follows: {INFILE | INDDN} {filename|*} [os_specific_options] [{BADFILE | BADDN} badfile_name] [{DISCARDFILE | DISCARDDN} discardfile_name] [{DISCARDS | DISCARDMAX} discardmax] The keywords INDDN, BADDN, and DISCARDDN exist to provide compatibility with IBM DB2, and are rarely used.
