I don't do other people's homework when I can help it. But here is a
challenge:

  Implement the following generic and demonstrate a working instantiation:

  generic
    type Index is (<>); -- Usually an index into an array
    with procedure Less_Than (Left, Right : in Index); -- Compares array
elements
    with procedure Swap      (Left, Right : in Index); -- Swaps array elements
  procedure Sort (Starting_At : in Index := Index'First;
                  Ending_At   : in Index := Index'Last);

Doug.
