I suspect that is part of it Jeri but if that is the case, why mark me down because I have experience and a distinction in programming at a lower level that in fact taught more than this module has rather than taking that into account? This was taught by the same college. Im not sure whether to feel insulted by having to put those lines together or whether to feel that the college does not rate its own teaching.

bflat has mentioned one very good reason for comments and I agree that programs can get to a point where comments are necessary, either to explain logic or simply to explain what loop within a loop (the official term for a loop is Iteration one of 3 basic and essential program constructs) is doing what. Even if I am just hacking for my own benifit I have to mark starts and stops of these to keep track of what begins and ends where so I do appreciate their value.
