/ANSI_FORMAT
  /NOANSI_FORMAT  (D)

  Indicates that the source program is in conventional ANSI format.
  The compiler then expects 80-character card image records with
  optional sequence numbers in character  positions 1 through 6,
  indicators in position 7, Area A beginning in position 8, Area B
  beginning in position 12, and the identification area in positions
  73 through 80.

  The default, /NOANSI_FORMAT, indicates that the source program is
  in VSI COBOL terminal format, where Area A begins in position 1,
  Area B begins in position 5, and the source program records do not
  have line numbers.
