Forth Day
November 2007 Meeting Notes

Compiled by Dave Jaffe

Contributions from Kevin Appert and others


Coffee and networking


Chairman's Welcome - George Perry


F# Tutorial - CH Ting
"I will give a short presentation on the F# implementation and how to use it in Windows applications. I will demonstrate a number of applications to show how F# makes use of Forth in a Windows environment."

F# Version 2.40
F# Version 2.41 with Tutorial - 366 Kb zip file


Audible Computing - Masa Kasahara
Masa will discuss his rationale for his Audible Computing project and how Forth might play an entirely different role in computer language history.

Slides - 1.9 Mb pdf file
Curtis keyer Chip


Forth Microcontroller for Education and Robotics - Glen Reuschling
Glen will report on his recent progress in building an FPGA-based Forth microcontroller with an integral USB host controller. He'll also present plans for using the controller in science education and robotics.

48 Mhz, 128 instructions, 3 to 8 clocks per instruction


Portable Embedded Forth Application Development - Leon Wagner
"I will demonstrate the development, debugging, and testing of a very simple embedded application using the SwiftX development environment. I will then show how this application can be moved across a variety of target hardware platforms with minimum modification."

Leon will be bringing copies of the newly published Forth Programmer's Handbook - 3rd Editionfor sale for $35 (tax included - cash or check only, no credit card purchases). Email Kevin Appert (forther -at- to reserve your copy.

The new and improved Forth Programmer's Handbook (3rd Edition) was just released by Forth, Inc. The book has been extensively revised and updated to reflect current programming styles and usage. Nearly 50 pages have been added, including enhanced descriptions of many features and new topics such as Forth cross compilers. This edition covers nearly 400 ANS Forth words and common extensions.

Forth Programmer's Handbook was written by two founders of Forth, Inc. for readers with a programming background but not necessarily prior experience with Forth. Offering comprehensive coverage of all major aspects of the Forth language - from basic principles to advanced concepts - the Handbook has become the de facto Forth reference manual for Forth programmers everywhere.

SwiftX - SwiftX Application Developmenton the top of the toolbar on the right
This paper demonstrates the development of a simple embedded application (a Morse code distress signal) using SwiftX. The application is ported to three completely different CPU types by changing only the hardware API code.
This download includes the project source files as well. It's a zip with the PDF plus source all in one.
