Yes, the Red Dragon Book did prove to be an excellent source, this
time after spending weeks trying to figure this out on my own and re-
reading chapter eight yet another time, it was quite clear.


Although section on compound conditional expressions (pages 500-503)
provided a superb solution, it seems that I was able to improve upon
the way to process control flow statements discussed on pages 504-506.
I found no use what-so-ever for the nextlist construct, thus my
solution was exactly this much simpler.


Another aspect that I improved upon (that would certainly be out of
the scope of the original author's intention) was that I found a very
simple way to generate optimal jump code on the first pass.
