My sincerest apologies for the earlier repetitive messages, but when I first sent them, I got a message saying they had not been delivered, so I persistently tried revising them to make them short enough to be deliverable. Alas, the messages did get through --- but only partially --- despite the server saying otherwise. So, sorry about the (unintentional) deluge.
I am posting the material to a website, and once that gets done, I'll simply send a message go this group giving the URL where the problem is described. Once again, sorry about the spam deluge. Gene
