Thanks for the welcomes! As for knowing about WILD, I did read Wikipedia's rather thorough (at least I thought was thorough) description.

I have now been reading the forum for a few minutes and I don't know any of the other abbreviations yet. I need to do some more studying.

@paradox-db3: you may not want the username sleepydvdr. It may not be welcomed everwhere. I often get chased off with pitchforks and have horseshoes thrown at my head.
