Also beware on input!

max -- is maximum linear address
i   -- geek counter, counts downto zero including;
       thus, number of loops is (max + 1)

better is to have *all* counts downto zero,
i.e. zero address access and

i = max /* number of loops is (max + 1) */
do {
  /* use */ stuff[i];
} while (--i);
