Do you inline this SubVI?

If my understanding of the LabVIEW compiler/optimizer is correct, if you were to inline that VI, every instance of that VI would be copied down into the code and the controls would all be optimized out. The case structure would also be optimized out leaving the 'normal' method for accessing resources. This would give you the less CPU usage overhead compared to format into string or a subVI call, while supporting the normal methodology used by the WPI Library.
