ahmad's point is however a good one. It is generally good practice to limit the scope of variables as far as is reasonable. It reduces the chance that a variable will be inadvertantly modified and the purpose of the variable is generally clearer.

I agree. However, he explained it as "To make your code works fine", and my issue was that the relevence could be misunderstood, being that the second point isn't going to make the code work any finer than it already did, or at least not in the way that the first point does. If that makes sense, that is.
