VARKON Version 1.16 1998-11-03

> ### f153 Display context sensitive help

> Description

> Displays help on the current context. Each context may have a specific helpfile in ASCII plain text (.txt) or HTML (.htm) format. The current context can be a menu, a function or a module. If a menu is active VARKON uses the menu number to decide what helpfile to display. Menu 48 for example will display m48.txt or m48.htm. If a function is active VARKON uses the number of the function. Function f127 will display f127.txt or f127.htm. If a module is active or being called or edited VARKON uses the name of the module. Calling my_module and activating help will display my_module.txt or my_module.htm.

> VARKON assumes that helpfiles reside in the DOC-directory of the current project. If not found there VARKON also searches the main VARKON_DOC directory, usually VARKON_ROOT/man where the VARKON documentation normally is installed in subdirectories v_man and m_man.

> In order to display HTML-formatted helpfiles the "html_viewer"-resource in the VARKON ini-file must be set to the proper HTML viewer. In the default ini-files distributed with VARKON for UNIX this resource is set to use Netscape for displaying .htm-files. The Windows95/NT version of VARKON defaults to InternetExplorer. You may have to edit the "html_viewer"-line in your ini-file if you want to use something else than default or if your Netscape- or Explorer-installation path is different from default.

> If the "html_viewer"-resource is not set VARKON can only display .txt type help files.
