Oh well thanks all of you. Writing a Biology test at university today but I will experiment with these functions a little when I'm done with that. Interesting when I learn programming, instead of memorizing syntaxes and procedure/function names and following methods, I just start writing something to experiment with it. I look it up in google if I need a func. or proc. see the syntaxes and correct methodical errors and I learn a lot easier this way. I can not imagine for example that I could have learnt the useage of binary files by just reading the book, and then I would have been able to use it correctly instantly. Altough for my programs written this way in the end I often find out there was a lot lot more easier way. Well often means almost always xD
