Re: A89: Copying data


ehm...  not to be rude.. but.  you are making mario.. and you can't even figure
out something like this by your self? something is wrong.. :/
but..  what the heck..  why not try this?
put the source adress in a0 and the destination adress (screen address) in a1
and the number of longwords-1 to copy in d0
and do this:

lbl:    move.l (a0)+,(a1)+
        dbra d0,lbl

but..  the ti89 screen is only in the upper left corner of the screenram, so you
have to add 10 to the destination after every line written..

so..  something like this?

       move.w #99,d1
lbl2:  move.w #4,d0
lbl1:  move.l (a0)+,(a1)+
       dbra d0,lbl1
       adda.w #10,a1
       dbra d1,lbl2   

with source in a0 and screenram in a1...
