scrollprecision as float = 0.25 :`// value between 0.00 and 1.00
scrolldepth = (mousemovez()*scrollprecision)
if mousemovez()=>scrolldepth then scrollwheel = inc scrollwheel
if scrollwheel > 12 then scrollwheel = 0
roughly how darkbasic works with the scroll wheel

only in DarkBasic Pro i've had some interesting results, as it works perfectly in Standard/Enhanced - but Pro has a different precision and operation system.
