Hi Chamara,

When you define a program with a prototype, you can then make use of the fabulous parameter keyword Const (amongst other keywords). Also, when you compile a program that calls the prototyped program (and it has the prototype), it will validate that the proper parameters are being passed (by data type anyway).
