I want to make sure that it doesn't use just part of the other elements in the union. If the compiler decides to use one byte for the bool (which it is perfectly valid to do so), and it happens to map over a zero of the other elements in the union, then it will give a false negative. By using unsigned long, it will be guaranteed to contain some content. -- Steve
