Common Desktop Environment: Help System Author's and Programmer's Guide

Command Options


Removes all files generated from any previous run of HelpTag for the given volume.


Causes the names of all generated files to be limited to a maximum of eight characters for the base name and three characters for the extension. This allows run-time help files to be moved to systems where longer names may not be supported.


Displays the progress of the dthelptag command and displays any parser errors that occur. Parser errors are also saved in a file named volume.err.


Uses the formal parser to interpret help files tagged with SGML-compliant markup. If not specified, dthelptag assumes the input file contains shorthand markup.

Because there are two types of markup--shorthand and formal--it is recommended to distinguish the types by using a file extension. Use.htg for shorthand markup and use.ctg for formal markup.
