C++ tagged unions continued

I have received indirect confirmation that using structs with tagged unions in C++ is not object oriented, as I suspected, and is most likely a poor way of doing things. This is a C method, not C++. No objects, no encapsulation. Not my idea to do it like that anyways. My idea used nice C++ objects. Oh well. I'm just low man on the totem pole and do as told. lol.
