Uh, wait.. Thought dot product in this case was the equivalent of matrix 
multiplication, that page implies that the vector results in a single 
value, not another vector... So, what I posted in my second reply to 
John was wrong?


-- 
void main () {

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