I am using html help in Ftn95 with clearwin+ in a very simple way, for example
i=winio@('%ca[PROGRAM Help]%bg[grey]%ww[thin_border]&')
I=winio@('%fn[Arial]%ts&',1.0D0)
i=winio@('%mn[Back,History,EXIT]&',
+ 'PREVIOUS_TEXT','TEXT_HISTORY','EXIT')
i=winio@('%pv%60.20ht@',helptopic)
The result is not very professional formatted html output window.

Now, I would like to use a .hlp Windows help file in my program. As far as I can see I can use the clearwin callback "help_contents" to display the content of the help file. Nevertheless, I also will display context sensitive help in special menus. How can I use my Microsoft .hlp file? Can I specify the topic title or the context number anywhere?

There is no direct ClearWin+ support for Microsoft .hlp files.
You can get context sensitive help using %`th but you must provide the help text in the code.
Additional options for %th are described in the notes for %di (see "Using dialog resources" in the FTN95 help file).

In order to use a Microsoft .hlp file, you need to call the Windows API function WinHelp which is listed in win32api.ins. This will enable you to access given topics in a help file.
