Don't you hate it? You've just got a new programming language and you're trying to write your first program. You want to use a certain feature (you know it's got to be there) and you can't find it in the manual.
I've had that experience many times. So in this manual you will find many short features on all kind of topics. How to input a number from the keyboard, what a cell is, etc.
I hope this will enable you to get quickly on your way. If it didn't, email me at 'hansoft@bigfoot.com'. You will not only get an answer, but you will help future Forth users as well.
You can use this manual two ways. You can either just get what you need or work your way through. Every section builds on the knowledge you obtained in the previous sections. All sections are grouped into levels. We advise you to use what you've learned after you've worked your way through a level.
If this isn't enough to teach you Forth you can always get a real good textbook on Forth, like "Starting Forth" by Leo Brodie. Have fun!
