my goodness David! I haven't read email for a while on this list and I
somehow certainly missed this one! and I certainly missed it the first time
around as well! somehow.
Man! that's amazing stuff you've got here to my book. Thanks soooo much for
expending the effort/energy/time to write all that one out.
It'd take some study for me to get all of it, as I'm very poor at whileLoops
comprehension myself really.
Thanks for this eh.
