Thanks for the FR education.
Glad to be of help on IBTZ (and IATZ too).
I have to add that I get a smile when Jim uses the KMA abbreviation (as he certainly had to do on this thread).
Why?
Well, when business travel takes me from Texas up through the midwest, there's a big radio station in Iowa that I tune in with the callsign of KMA. Every time they do a station ID and proclaim K-M-A, I can't help but think of Free Republic. :-)
