"Yet Another Recursive Decompiler," 1985 FORML Conference Proceedings. Describes a Forth decompiler, written in Forth.

"Forth and the Rest of the (DOS) World," Forth Dimensions, Volume XV, Number 4 (November-December, 1993). This paper also appeared in the 1993 FORML Conference Proceedings. Describes a technique for turning an executable Forth image into a standard object file (.OBJ format) so that it can be made into a standard executable (.EXE format) with a standard linker (e.g., Borland's TLINK). Also describes how to use this technique to link foreign functions to the Forth dictionary, making C (and other) libraries available to Forth programmers.

At FORML this paper received an award for "Featured Paper on Forth with Benefit to the non-Forth Community." Its publication in Forth Dimensions earned second place in a contest on the topic of "Forth Development Environments."

"Forth in 32-Bit Protected Mode," 1993 FORML Conference Proceedings. Describes a straightforward technique for implementing a 32-bit flat model Forth launched from DOS using DPMI.

"DPMI Forth Revisited," 1994 FORML Conference Proceedings. Further discussion of the relationship between 16-bit and 32-bit Forth code connected through the DOS Protected Mode Interface.

"Forth in 32-bit Protected Mode," Forth Dimensions, Volume XVI, Number 5 (January-February, 1995). Revision and combination of the two previous papers.

"Switch Suggestions," Forth Dimensions, Volume XVI, Number 4 (November-December, 1994). Letter on a method of implementing a C-like "switch" in Forth.

"RETRY, EXIT, and Word-Level Factoring," Forth Dimensions, Volume XVII, Number 4 (November-December, 1995).


For the past several years I've been maintaining, re-developing, and extending a large DOS-based database management system in Forth, including re-writing the compiler, developing multi-user database access, implementing context sensitive help, etc.: up and down the environment from user-interface to system calls, 15-20 megabytes of source code in blocks in a 16-bit environment necessarily optimized for space. All this is interesting, but a little repetitious.

Unlike many Forth programmers, I'm more interested in languages and systems than in hardware. I've been exposed to Windows programming with Win32Forth and, to a lesser extent, LMI WinForth. I'm familiar with a number of other programming languages and their paradigmatic differences, and been most fascinated by Java, Delphi, and Prolog, and by C++ when it was straightforward and new.

I would prefer to work in Forth, particulary a 32-bit ANS compliant object-oriented Forth on a Windows platform. I would be almost as happy (perhaps happier in the long run) with Java, which I see as a programming language, not just an applet generator. As a Forth programmer I'm impressed with Java's simplicity and power, which rival Forth's, and with its popularity, which means so many things, including the possibility of supplanting C++ as the dominant development language. My third environmental choice would be Delphi, for its ease of use and native-code power.

I have, at this point, only home-based, recreational familiarity with Java and Delphi, enough to convince me of their power and to give me a toehold on the learning-curve. I count on the fact that I am a fast learner, particularly with things I enjoy.
