I have an Excel post position "study" that I've done which I want to send to you. When I try to put it in a private message, it is too big to look at in any meaningful way. May I have your e-mail address? I think that I'll be able to attach it to a regular e-mail.
Go tot he Follow Ups and look through the early ones - in his computer columns.
Maybe the one about the third fractions, or the one about the new class ratings.
He mentions how to clear things out and write new programs, change batteries, etc.
