Need help looping a script

[benergy]

I'd like to loop the following script that I found on this forum. Would anyone be kind enough to check my code for errors? I just need the mouse to move continuously, and I'd like to be able to press F10 to start and stop the movement. Currently, when I press F10, nothing happens. Thanks!

And for what game is this for ?  What is the purpose of this mouse movement ?
