Invokes the CDA Viewer, which lets you view a compound document
   file on a character cell terminal or DECwindows display.

PARAMETERQUALIFIERS

Example

input-file
   Specifies the name of the file to be viewed. If you do not specify
   an input file name, you are prompted for one. You cannot use
   wildcard characters in the file specification. The default input
   file-encoding format is DDIF, and the default file type is DDIF.
   Valid input file formats are any of those for which there is a
   front end installed on the system.

Additional information available:

/FORMAT/HEIGHT/INTERFACE/OPTIONS/OUTPUT/OVERRIDE_FORMAT
/PAGE/WIDTH

      /FORMAT[=format-name]
      /FORMAT=DDIF (default)

   Specifies the format of your input file. The input formats that
   you can use with the CDA Viewer depend on the CDA converters
   installed on your system. The default input format is DDIF. Input
   formats bundled with the VMS operating system and their default
   file extensions are as follows:

   Input Format     File Extension

   DDIF             .DDIF

   DTIF             .DTIF

   TEXT             .TXT

   PS               .PS

   Additional input formats are provided in Digital's CDA Converter
   Library, a layered product. Independent software vendors who write
   DDIF- and DTIF-conforming applications and front and back ends
   also provide input formats that are layered on the VMS operating
   system. Contact your system manager for a complete list of input
   formats available on your system.

      /HEIGHT=nn

   Specifies the height of the page in number of characters. If
   you specify the /OVERRIDE_FORMAT qualifier, or if the document
   being viewed has no inherent format, this page height is used. On
   the DECwindows display, the default height is 66 lines, which is
   equivalent to the default page height of 11 inches. On character
   cell displays, the page height defaults to your terminal's screen
   height. However, if you use the /OUTPUT qualifier, the page height
   depends on the page height of your document.

      /INTERFACE=DECWINDOWS
      /INTERFACE=CHARACTER_CELL (default)

   Specifies the type of display you are using.

      /OPTIONS=options-filename

   Specifies the name of a file that contains processing options.
   The default file type for a VMS options file is CDA$OPTIONS.
   This qualifier is used only with input formats for which you can
   specify processing options.

      /OUTPUT[=output-filename]
      /NOOUTPUT (default)

   Specifies a file that you want to receive the output instead of
   having it displayed on the screen. You cannot use this qualifier
   when you have specified /INTERFACE=DECWINDOWS.

   If you specify /OUTPUT but you do not specify a file name, the CDA
   Viewer creates a file with the same name as your input file but
   with a file type of LIS. If you specify /OUTPUT, you cannot also
   specify the /PAGE qualifier.

      /OVERRIDE_FORMAT
      /NOOVERRIDE_FORMAT (default)

   Controls whether the CDA Viewer overrides the format of your
   document or uses the formatting information stored in your
   document.

      /PAGE
      /NOPAGE (default)

   On a character cell terminal, this qualifier determines whether
   the output display of the CDA Viewer pauses after displaying each
   page of your file. If you specify /PAGE, you can page backward
   and forward, or jump to the top or bottom of the document. Note
   that if you specify /PAGE, you cannot specify either the /OUTPUT
   qualifier or the /INTERFACE=DECWINDOWS qualifier.

      /WIDTH=nn

   Specifies the number of characters per line. If you specify the
   /OVERRIDE_FORMAT qualifier, or if the document being viewed has
   no inherent format, this page width is used. On the DECwindows
   display, the default width is 85 characters, which is equivalent
   to the default page width of 8.5 inches. On character cell
   displays, the page width defaults to your terminal's screen width.
   However, if you use the /OUTPUT qualifier, the default is 132
   columns.

   $ VIEW FILEA.DTIF -
   _$  /FORMAT=DTIF -
   _$  /OPTIONS=OPTIONS.CDA$OPTIONS -
   _$  /NOOUTPUT -
   _$  /NOPAGE -
   _$  /INTERFACE=DECWINDOWS -
   _$  /OVERRIDE_FORMAT -
   _$  /WIDTH=80 -
   _$  /HEIGHT=66

     This command invokes the CDA VIEWER to view a file named
     FILEA.DTIF, which has the DTIF format. The display interface
     is DECwindows, and the CDA VIEWER will override the document's
     default format. The display width will be 80 characters, and
     the display height will be 66 lines.
