Also remeber that OVER 1 does XOR, OVER 2 does AND and OVER 3 does OR ;-)
Read help on OVER: <!-- m --><a class="postlink" href="http://www.boriel.com/wiki/en/index.php/ZX_BASIC:OVER">http://www.boriel.com/wiki/en/index.php/ZX_BASIC:OVER</a><!-- m -->

AND + OR are used to create "Filmation Effects" (Alien 8, Knight Lore, Wally, etc)

So, in theory, only using OVERs background can be preserved, right? At least for basic sprites.

Cheers

EDIT: or better, use this? <!-- l --><a class="postlink-local" href="http://www.boriel.com/forum/how-to-tutorials/topic390.html">how-to-tutorials/topic390.html</a><!-- l -->
