If that is the case, then the answer is to download a current version of Mach3 and buy the full licence. If it is not Mach3, then that's not the answer!
I don't think it's Mach3 because Mach3 has a code line limitation, not number of commands, and the number of lines is limited to 500, so it is pretty useful for small jobs and test running.
