This Part of the on-line book deals with the On-line Help System.
The On-line Help System is a sophisticated system for creating on-line help from your character-based applications, and displaying it on screen. The system includes facilities to allow extensive navigation around the available information.
You can choose between using the native Windows format help system or the Micro Focus format help system.
The On-line Help System displays formatted text files containing information for application users. The system has two parts:
You use Ohbld to convert the specially formatted text files containing the help information for your programs into an on-line help file of compressed topics accessible to the On-line Help Viewer. (See the Glossary for a definition of the word topic.)
The On-line Help Viewer displays topics from all available on-line help files and allows extensive navigation around the files. These hypertext capabilities lead to the program name of Hyhelp. Hyhelp uses a function key interface, and is for use with character applications.
Topics can contain cross-references to other topics which the user can select and action. Index, contents, bookmarks and a history list all provide additional navigation to allow the user to access quickly the information required. Alternatively, the user can browse through the information at leisure. Selected topics or parts of topics can be printed or placed into a text file for use elsewhere.
Topics can be presented in windows of differing sizes (as selected by the application) without the need to scroll sideways.
The chapter On-line Help Viewer (HyHelp) describes what the On-line Help Viewer is, its functions, how to invoke it and how to use it for viewing the NetExpress Help.
