Robert, Thanks for the "Article". It looks very interesting. Is there any way to get a copy of the whole thing as a printable PDF or single HTML file? I have difficulty reading long stuff on crt-screens -- high-contrast black-on-white paper works much better for some reason. (I apologize to the spirits of all the trees that die because of my affliction. I can only plead necessity.) Thanks, Rick "Robert G.
