output ASM

I also noticed with:

IF (available = 1) or (available=2) or (available=4) or (available=8)

that the code doesn't do short-circuit testing with OR - it's possible, here to do

Short-circut evaluation is not yet implemented, neither is tail recursion (I would like to implement both of them). Of course, it might make your program bigger, but I think it's necessary.
