Hello Arno,

thanks for the explanation! I have one more question: on the python
site it says it's better to replace the system commands by subprocess
and Popen.
Now I searched for some good example for my specific case (as I have
no idea how it should work and I don't get it any clearer by reading
http://docs.python.org/3.0/library/subprocess.html#module-subprocess)
and I found this:

> import subprocess
> def clear():
>     subProcess.Popen('clear')

But it just doesn't seem to work. Would you have any idea how it would work?

Once more thanks for the first answer,

Devilly

I was just wondering where I can find al the commands which can be used for os.system(). I searched with google but I didn't find an answer. In the official python tutorial it says os.system('command') executes the command, but it doesn't say which commands exist (or I'm just blind).
