VUhU1 are the four arithmetic operations (+, > -, x, /). But I just don't get the other ones. It's just meant to be pedagogical: the idea is that you should learn the VUhU1 before the VUhU2 and so on. But of course mistakes may have been made (I think VUhU3 is too high for unary minus). VUhU0 is as you say the no-ops. Don't worry about it. -- You received this message because you are subscribed to the Google Groups "BPFK" group.
