CDA(5) File Formats Manual CDA(5) Name CDA - Compound Document Architecture Description Digital's CDA architecture for compound documents is an open architecture that establishes a framework for the interchange of many types of data in a multivendor environment. Utilizing CDA converters, compound revisable format data can be handled much the same as ASCII text. With CDA converters, you can write applications that handle compound documents, regardless of the environment in which you or application users are working. CDA includes the Digital Document Interchange Format (DDIF), the Data Object Transport Syntax (DOTS), and the Digital Table Interchange Format (DTIF). Each of these formats is encoded using the Digital Data Interchange Syntax (DDIS). Using these representations, CDA pro- vides a method for manipulating files that contain a number of integrated components. The tools associated with CDA include the CDA Toolkit (libddif.a), the CDA Converter (the main converter is and the CDA Viewers. The CDA Toolkit is a collection of routines that support the creation of CDA applications. The CDA Converter converts files of a specified input format to a specified output format. The CDA Viewers are used to display CDA-encoded files on a workstation display or character cell ter- minal. All of the following products support CDA-encoded files. If you only intend to manipulate CDA files, and do not have an interest in the particulars of the file format, you can use any one of these products to manipulate a CDA-encoded file: CDA Converters CDA Viewers (dxvdoc, vdoc) dxcardfiler dxmail dxpaint PrintScreen See Also cdoc(1), vdoc(1), DDIF(5), DDIS(5), DOTS(5), DTIF(5) Compound Document Architecture Manual CDA(5)

vdoc(1) General Commands Manual vdoc(1) Name vdoc - invokes CDA Viewer for character-cell displays Syntax vdoc [ -f format ] [ -O options_file ] [-r] [-w paper_width] [-h paper_height] [-p] inputfile Description The command invokes the CDA Viewer that enables you to view the inputfile on a character-cell terminal. If inputfile is not specified, reads from standard input. Options -f format Specifies the format of inputfile and invokes an appropriate input converter as part of CDA. The ddif, dtif and text input converters are provided in the base system kit. Additional converters can be added by the CDA Converter Library and other layered products. Contact your system manager for a complete list of the input formats supported on your system. The default format is ddif. -O options_file Names the file passed to the input converter to control specific processing options in that converter. Refer to your documentation set for a description of converter options. The options file has a default file type of .cda_options. Each line of the options file specifies a format name that can optionally be followed by _input or _output to restrict the option to either an input or output converter. The sec- ond word is a valid option preceded by one or more spaces, tabs, or a slash (/) and can contain upper- and lowercase letters, numbers, dollar signs, and underlines. The case of letters is not significant. If an option requires a value, then spaces, tabs, or an equal sign can separate the option from the value. Each line can optionally be preceded by spaces and tabs and can be terminated by any character other than those that can be used to specify the format names and options. The syntax and interpretation of the text that follows the format name is specified by the supplier of the front and back end converters for the specified format. To specify several options for the same input or output format, specify one option on a line. If an invalid option for an input or output format or an invalid value for an option is specified, the option may be ignored or an error message may be returned. Each input or output format that supports processing options specifies any restrictions or special formats required when specifying options. By default, any messages that occur during processing of the options file are written to the system standard error location. For those input formats that support a LOG option, messages can be directed to a log file. -r Specifies that the CDA Viewer is to override the format of the document. If the -r qualifier is not specified, the CDA Viewer retains the formatting information stored in the document. -w paper_width Specifies the paper width in units of characters. The -w qualifier always specifies the fallback formatted document page width to be used when the -r (override format) qualifier is specified or when the document has no inherent format. When used with the -p (page mode) qualifier, the display page width is determined from the terminal and is unrelated to the formatted page width. In nonpage mode, the specified -w value is used for both fallback document page width and the display page width. If the -w qualifier is not specified, the default width is 80 characters. -h paper_height Specifies the paper height in units of characters. The -h qualifier always specifies the fallback formatted document page height to be used when the -r (override format) qualifier is specified or when the document has no inherent for- mat. When used with the -p (page mode) qualifier, the display page height is determined from the terminal and is unre- lated to the formatted page height. In nonpage mode, the specified -h value is used for both fallback document page height and the display page height. If the -h qualifier is not specified, the default height is dependent on the docu- ment. -p Specifies that the CDA Viewer is to pause after displaying each page. The user can also page backward and go directly to the top or bottom of the document. If the -p qualifier is not specified, the CDA Viewer displays each page without pausing.
