	I want to make a textscroll routine, that uses blitter. I have an off-
screen bitmap from which the characters should be copied to the on-screen
bitmap. How is this routine actually made? I think I have to use bit shifts and
masks but how? 
	Another question. I saw once a demo source, which initialized an
interrupt routine to the address $6C (autovector, level 3). What's the meaning
of it? Could it be useful for my textscroll routine ?
