  DIRECT = dir

  dir  Is a character scalar memory reference that is
       assigned one of the following values:

  'YES'       If the file is open for direct access
  'NO'        If the file is not open for direct access
  'UNKNOWN'   If the processor cannot determine whether
              the processor is open for direct access
