Paul,

I think you are getting to close to issues which Harv is loath to lay aside. Let us not make any claims on what I do. Let us rather take the position that we need to communicate the central concept. You have a mathematical mind and many things which may seem very clear to you are not at all clear to Harv.

And Harv, don't go off the deep end. Until you understand what I have done, don't worry about what you perceive as the problems. Believe me none of the issues you bring up are real problems; but we will get to that some time later.

Personally, this has been a very good experience. There is nothing more beneficial to understanding than trying to explain something.

Have fun -- Dick
