Program, Test, Program, Test - Bill Ragsdale
This presentation will cover a method to intersperse testing and coding. The testing co-resides with the code but is selectively activated. Once the work is complete, the test cases become mute. If code changes are made, the testing can easily be reactivated.

True Object Oriented Forth: ooeForth - CH Ting
"Chochain Lee helped me shorten the Forth source code to 398 lines to which I added a very simple Windows interface, making it the smallest Windows Forth! In ooeForth all Forth words, integers, strings, and address literals are objects and all colon words have linear object lists."

Forth Synergy - Brad Nelson
"Forth is notoriously the language of the lone wolf. Its power to build domain specific mini-languages means many problems can be expressed beautifully and succinctly. Unfortunately, it often also yields idiosyncratic code, inscrutable to all but a single author or comprehensible only after careful study. This makes it a challenging language for collaborative development, and unheard of in settings where hundreds or thousands of hands touch a codebase."

"I'll explore some approaches to modules, modularity, data structures, and data passing that attempt to tame some of Forth's solitary peril, while retaining the strengths that make it unique."

Remembering the Kestrel-1 - Samuel A. Falvo II
"This talk will be an attempt to archive what I can recall or find about my very first Kestrel computer design in 2004, and if time permits, where I wanted to take that design but never did."

Forth Challenge: Data Structures - Bill Ragsdale
This month’s challenge is an exercise in creating a data structure. (That data structure will be applied in next month's Challenge.) Create a table with four columns with the values for Degrees, Radians, Sin(ref), and Sin(comp) running from 0 degrees to 360 by 22.5 degree increments (17 entries). The reference Sin(ref) should be manual entries from a known source. Sin(comp) is computed (or using system resident capability). Use any method to express the values, possibly expressed as scaled integers, ratiometric, floating point, or something else.
