It looks like it might be a partial rewrite, to be honest. It's supposed to solve the motion of the planets in the solar system, at the moment as far as I can tell all it does is send everything flying off in completely straight lines. To me, it makes no sense, but I shall investigate more. It's not like I don't know the maths, I've done it before, but I've never written a program this size in C. It's getting rather complex and I am a little worried.

Of course there is also the question of do I get help from the internets, it is somewhat part of my Senior Honours project. If after the weekend no progress has been made I'll start posting snippets, but for the moment I'll sulk. I've no idea where it's going wrong.
