What's the oldest app still running?

Random thought while I was walking home from the grocery store today -- I wonder what is the oldest app still running (and doing something useful)? I'm assuming it would be in the banking or insurance industries, but I'm curious. I have a friend who's still working on something written ~30 or so years ago in PL/1, a language that pre-dates many developers in this field. (Oh, and despite the age of TCP and SMTP, I wouldn't count them -- they're protocols, not apps. I'm the one with the random question, I can make the rules.)

Easy: SABRE -- the Semi-Automatic Business Research Environment -- conceived in 1953, started in 1957, launched in 1960, and still one of the largest "Global Distribution Systems" (aka airline reservation systems) in the world.

Yow! That is old.
Thank you Larry (and yes, I am still giddy that you read my blog -- honest)
