Hello everyone,

Thanks for the responses I have recieved concerning my previous question 
about 'dirty stuff'.  What is the best method for updating only the 
portions of the screen that have changed without having the screen 
flicker?  If for example I am in 640x480x256, would i use two 480 arrays 
corresponding to the minimum and maximum position to update for every 
line? Or is there a better way that would allow much more precise 
updating?  If so, could someone please explain to me the full procedure.

Thanks a lot,
	Tony
