return

createSchedule([[math109]], fall, Out).
[[cs485, cs485], [cs355, cs355, cs462, cs462, cs462], [cs345, cs345, cs352, cs352, cs352, cs362, cs362, cs362, cs396, cs396, cs396], [cs330, cs330, cs330], [cs255, cs255, cs255, cs268, cs268], [math114, cs245, cs245], [math112, cs145, cs146], [math109]]

Out = _G431

this is what prolog returns and the list of lists is shown by using write(Out) in prolog.

Any ideas why it is showing this? Thanks
