vdoc(1) General Commands Manual vdoc(1) NAME vdoc - invokes CDA Viewer for character-cell displays SYNOPSIS vdoc [-f format] [-O options_file] [-r] [-w paper_width] [-h pa- per_height] [-p] inputfile OPTIONS Specifies the format of inputfile and invokes an appropriate input con- verter. The DDIF, DTIF, and Text input converters are provided by the DIGITAL UNIX system. You can add additional converters by purchasing layered products. Contact your system manager for a complete list of the input formats supported on your system. The default format is DDIF. Names the file passed to the input converter to control specific pro- cessing options in that converter. Refer to your documentation set for a description of converter options. The options file has a default file type of Each line of the op- tions file specifies a format name that can optionally be fol- lowed by _input or _output to restrict the option to either an input or output converter. The second 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 op- tion requires a value, then spaces, tabs, or an equal sign can separate the option from the value. You can precede any line by spaces and tabs. To terminate a line, use any character other than those 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 op- tions 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. 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. Specifies the paper width in units of characters. The -w qualifier always specifies the fallback for- matted document page width to be used when the -r (override for- mat) 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 dis- play page width. If the -w qualifier is not specified, the de- fault width is 80 characters. Specifies the paper height in units of characters. The -h qualifier always specifies the fall- back formatted document page height 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) quali- fier, the display page height is determined from the terminal and is unrelated 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 document. 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. DESCRIPTION The vdoc command invokes the CDA Viewer that enables you to view input- file on a character-cell terminal. If inputfile is not specified, vdoc reads from the standard input.
