Opening a File

  The Open window opens automatically when you start the
  CDA Viewer application.  The input file you select will appear
  in the CDA Viewer window, and the Open window will
  disappear.

  To display a new file, click on the Open...  item in the File
  menu.  The current file display will close automatically when
  you click on the OK button in the Open window.

  In the Open window, do the following:

  1.  In the Directories list box, click on the name of the
      directory that contains the file you want to view.

  2.  In the File Format list box, click on the format name (also
      called the keyword) that applies to the input file.  Or, you
      can type a format name in the File Format entry box.

      If you select an input format other than DDIF , you must
      enter a format for which an input converter exists.

  3.  (Optional) Click on the Options File...  button to open the

      Options File window.  Specify the name of a file containing
      processing options to apply to your input file while it is
      processed for display.

  4.  (Optional) Click on the Display Options...  button to open
      the Display Options window.  Specify a paper size to be
      used to display your input file.

  5.  In the Files list box, double click on the name of the file;
      or click on the file name and then click on the OK button.
      By default, only DDIF files are displayed unless you select
      a different input format.

  6.  In the Open File entry box, you can type the name of the
      input file instead of selecting it from the Files list box.

  7.  In the File Filter entry box, you can change the list of file
      names displayed by typing a new Filter specification and
      clicking on the Filter button.

  8.  Click on the OK button to complete selection of the input
      file name and format, or click on the Cancel button
      to close the Open window and go to the CDA Viewer
      window.
