Re: A89: New To 89 Assembly -3 Questions-
list of romcalls comes in the documentation of the shells..
the second plane is no fixed address, you allocate memory for it. the address
for the allocaded memory is for doorsos putted in graphlib::plane1
(the first plane is in graphlib::plane0)
and.. to ldir on the 68k you kan use move.b (a0)+,(a1)+ , move.w (a0)+,(a1)+ or
move.l (a0)+,(a1)+ to move a byte, word, or longword respectivly and then put
this in a small loop:
move.w 99,d0
loop:
move.w (a0)+,(a1)+
dbra d0,loop
this moves _100_ words from (a0) to (a1)
