    OK.
    I tried the program to see if the register A is less than register B

    A < B is R0 where
    R0 set (if B=0 then C:=0 else R3)
    R1 set (B:=B-1, A:=A-1, R2; B:=B+1, A:=A+1)
    R2 set (if A=0 then C:=1 else R0)
    R3 set (if A=0 then C:=1 else R1)

    Is that correct? And if A and B are 0?
