The DISPLAY statement transfers low-volume data from the program to
  the default system output device or to the object of a mnemonic-name.
  The HP extensions to the DISPLAY statement (formats 2 and 3) are
  COBOL language additions that facilitate video forms design and data
  handling.

      [ AT {|                              |} ]
      [    {| COLUMN NUMBER { column-num } |} ]
      [    {|               { column-id  } |} ]
