It is simply an illustration that proves that it is _possible_ to generate accurate code with C. It is also possible with assembly language. However, doing so requires good programmers with plenty of experience. You can get equal quality from poorer programmers with less experience by using Ada. I leave it to you what you will get with experienced good programmers and Ada. -- [mail]: Chuck F (cbfalconer at maineline dot net) [page]: Try the download section.
