I will add them as time permits, but this was not a priority, I only implemented what we needed to test our robot. Alternatively, you may want to patch it and give me access to the patches so that I can integrate them :-) Be careful, it is not complete at all and even lacks some basic words.

I was a Forth guru back in the TRS-80 days, but I seem to have forgotten most of it. In any case, I grabbed it from the web site, and it compiled on the second try. I'm going to dust off my Forth books and see if I can make it do amything useful. blc I like it. I was a Forth guru back in the TRS-80 days, but I seem to have forgotten most of it.

Forth is such a beast. For example, we could interface with four words: move, turn, moving and ms (for milliseconds). Testing a path with the robot was as simple as typing: <blockquote><code>: end-of-move begin moving while 50 ms repeat ; : full-move move end-of-move ; : full-turn turn end-of-move ; : side 100 move 90 turn ; : square side side side side ; square </code> </blockquote> The robot would then make a square of 100 millimeters by 100 millimeters, waiting for the completion of each move before launching the next one, and ensuring 50ms pauses between successive pollings of the moving status to ensure that other tasks can be scheduled as well.
