An Adress Error occurs when you try to read a word or a longword from
an odd address. I think that's because the whole memory is divided into
2-byte chunks (since the whole 68k architechture is 16-bit).

Now, what is this?? "#str 8,a0"?? What are you tring to do?
Make A0 point at str...? Then it should just be "move.l str,a0"
or "lea str,a0", or even better, put (PC) after str, like

 lea str(PC),a0

as it's smaller & faster.

As to where in the code the error lies, I can't find. You've managed
to make a darn complex program with so few rows... congratulations :)
