Ok. My response was blocked because it was too long. Sorry I didn't know about the line limit. Thank's to all the folks who responded. I think I have the info I need. As for returning to SAC. Certainly do want to and hope I'll be in a position to do so in the new year. - Peter. -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
