Well, thats is not so easy. The treegenerator is much more complex. To get your hand on it, you have to understand it, and that is really an intellectual challenge. The functions are fully discribed in the standard handbook but they depend on each other. A statement like: Take this slider and you will get this result, is nearlly impossible. This means not, that it is at all impossible, but it would be a much larger and not so easy tutorial. Johannes
