Thanks for your reply.  Also, it isn't a compiler specific request.  I
was just asking how I share variables through multiple cpp files.  I
figured it out though.  I delcared it in my main application cpp file,
then I used extern variable to access it in all my other ones.  Thanks
again for the reply though.
