The Z will come into functionality later on down the road. This is only the
first phase of the idea I have for this program. I am wanting to build more
functionality into it later, and am trying to keep doors open. Thanks for
all the help everyone. I have the prototype working and will post it for you
guys to play with when I get a bit more functionality built in.
