Please put your code in code blocks.

interesting? what about a code tag ?

personally I would prefer to have a value-return function with only 1 exit point.
It would be easier to trace things up when debugging.

For this instance, it wouldnt make much different, however it would be a lot more difficult in bigger project.

that's just my preferences.
