This example is a generic procedure for constrained array types.

type Element_Type is private;

type Index is (<>);

type Collection is array(Index) of Element_Type;

with function "<=" (Left, Right : Element_Type) return Boolean is <>;

procedure Swap(Left, Right : in out Element_Type) is

Temp : Element_Type := Left;

Note: This example relies on [[Sorting_algorithms/Bubble_sort#Icon| the supporting procedures 'sortop', and 'demosort' in Bubble Sort]]. The full demosort exercises the named sort of a list with op = "numeric", "string", ">>" (lexically gt, descending),">" (numerically gt, descending), a custom comparator, and also a string.
