Okay, BS(!) and LJ8, thanks for your help. Next time I'll ask Mike.

doc, that's what my daughter, 28 this year, tells me: "Dad, it's ALWAYS been that way." Well, no. You're probably right about bic, though.

Faldage, I don't think I'm talking about an abbreviation here, although that may explain it. I'm trying to think of an analogous example, and I'm failing. Looks as if I'm going to have another high horse shot out from under me.
