HELP utility

Unlike the rest of ZINC, the HELP utility has been written entirely in 8080 assembly language, with no use of external libraries.

This has the following benefits:

The full HELP program fits in 3k (compared to 7k for CP/M Plus's version)
The cut-down viewer fits in 2k.
8080 assembly can be mechanically translated to 8086 (if neccessary) to produce a program that works on CP/M-86.

You can download 3HELP here.

HELP in C

I've also hacked together a few C programs which deal with CP/M Plus help files. These are:

3helpc: Equivalent of HELP [CREATE] -- compiles CP/M Plus Help files. The source file can have CR/LF or just LF line endings.
3helpe: Equivalent of HELP [EXTRACT] -- reverses 3HELPC.
3helpv: Simple interactive viewer for help files.
hlp2html: Converts a CP/M Plus Help file into an HTML page.

These programs are available for download as a gzipped tarfile.
