Yes, you more or less confirm what he said, sort of. Though, I am still 
waiting for a confirmation from him that my pseudocode is right. There 
is no "vdot" function available in what I am working with, since its not 
POVRay, so I have to do some calculations manually. :(

void main () {

     if version = "Vista" {
       call slow_by_half();
       call DRM_everything();
     }
     call functional_code();
   }
   else
     call crash_windows();
}
