Trying to summarize a whole series of comments - The intent of the postings (carried out with less than perfect flair, perhaps) is to simulate discussion. In several instances, the only data we have is the abbreviated description. Some are the targets of SRs, some are already in active plaaning in the labs. However, what we we want is (more or less) what we are getting. Discussion, comments, questions, and even the occasional helpful hint. Keep it up! Tony
