Prolog is such an Ass

It is irritating enough that I have to rush out a report, and to make things worse, the program does not run as I've expected.

Out of boredom, I've randomly typed nonsense and all it replies is "no". Well, Prolog is not a very good companion in lonely hours at night.

Of course I know the reason it returns 'no' in this case, but I wonder how to solve the infinite recursion that my gpaForcast gets into. ARRGH.

Good News: Tomorrow's 201 lab does not have a quiz (one quiz down in a way), and I've obtained an A for both the previous 203 lab quizzes, though that's the average grade.

Bad News: I need to get this freaking 301 prolog program and its report, as well as 203's report, before I can proceed to study for the exams!
