Dear hev: Thanks for a post to reply to. I have a remarkabler command of the obvious, but at the moment cannot think of a name for it. I believe there is a term for it in the byu.edu rhetoric site. But there are so many terms there, it takes a lot of patience. If you use Yahook just typing the above into the search box will bring up the site. I'll go look for URL to add as PS, but by the time I get back somebody else will have posted it.
