Hello Tristan, That’s nice. Please can you explain how to do it? I know that there are some article thats describe also how to compile forth under windows. It had a simple guideline. I have that uses for playing with the fp packages. And that was working fine. But I have removed is from my computer !!
Please someone can help me out with this.
