(I couldn't find the routine on my PC, and hadn't time to go into the
internet...)

So this tilemaproutine, copies the previously generated screen to the LCD
while making a new one? Must have been some trouble to make...

You also needed to make use of a tilemaped game/program to make this work
off course...

Okay we do have spriteroutines, but they are variable width/height
spriteroutines (tilemaps need fixed sized sprites). And the other graphics
routines are ones to draw circles, fill parts of the screen, etc. Not
really things where a tilemap-routine would be handy...

It can be something to think off for putting into the compilers-library
(but not for greyscale I'm afraid).
