The 'carriage_control' is a value that  indicates  the  carriage
  control  format  for  the file.  The value LIST indicates single
  spacing between components.  The values CARRIAGE and FORTRAN are
  equivalent and indicate that the first character of every output
  line is a carriage  control  character.   The  values  NONE  and
  NOCARRIAGE indicate that the file has no carriage control.

  LIST id the default for TEXT and VARYING OF  CHAR  files,  while
  NONE is the default for all other file types.
