The biggest complaint I have with the original example is that you've writen code to "do stuff" with array G, yet that code cannot directly be used to do the same stuff to some other array. In this sense, the code is not reusable. If it accepted G as a parameter, then it would be more general. The main advantage of globals is convenience (for example, if all you care about is getting this particular program working as soon as possible).
