  File Status:  21
 
  Reason:       For sequentially accessed files only: indicates a
                sequence error. The ascending key requirements of
                successive record key values has been violated, or, the
                prime record key value has been changed by a COBOL
                program between successful execution of a READ statement
                and execution of the next REWRITE statement for that
                file.
