Good, you found it yourself.

The order of S, N, W, E does not matter.
I personally would try to implement flood fill with iteration than recursion. And mind the borders x < 0, x >= W...

    this did it
    c := ASR(c, x MOD ppw * 4) MOD 10H;
    with no (-) complement
    No, I wonder how much it matters, the order of directions, we pick,
    e.g. S - N  - W - E?
