 does the address that a0 points to precede the address that a1 points to?

right after i replied, i think i figured out how you got confused.  Olle said
something like if you want to keep the information in a0, then you use a1, and
so on.  you must have interpreted this as him saying that to find the info in
a0, you can look in a1, but that is not what he meant.  he was answering your
question about why everyone uses a0 and d0 so much.  because they are the
"first" ones, it is easier to remember which registers you used, and when you
use a0, you naturally should use a1, then a2, and so on.  i hope i haven't
just confused you more!
