Thanks so much for the help. There are some nice guys in the world. Sincerely, I do appreciate the help. I am having some fun with this, it marries two of I passions, computers and woodworking. I've already tackles some screen mods for Mach3 and they actually work! Been doing a lot of reading and some trials, not unlike some other programming I have done in the past, as i get a better understanding of mach3 and g-code this will be a lot of fun. Thanks again to both of you.
