MS DOS Programming Systems

Holon86

Forth IDE for DOS applications, particularly suited for x86 embedded PC development. Holon86 is also useful for studying Forth, both the language (all words of the application system are presented in the browser) and the inner machine (single step through the program down through the kernel and 'next').

Holon11

Forth IDE for 68HC11 micro controllers.

HolonJ

Forth IDE for the Java virtual machine (JVM).

HolonX

Universal source handling tool.

DOS Box

The systems still work fine in a DOS Box.

About

Holon86 was my main development system for many years, both for developing client projects and to create the other DOS Holon systems. The systems were available as shareware for a while and have found good use in development and teaching environments. Holon11 particularly proved useful for teaching microprocessor programming, due to its interactivity and its facility to single step through machine code.

Now all systems are offered for free use - without support...
The source of the development systems themselves is available on personal request.
