Sure. That's a pretty typical Y2K fix. And it's basically what you do as a
human when looking at a two-digit year. (If I tell you that the expiration
date on my driver's license is 12-30-02, you assume 2002. If I tell you
it's 12-30-98, you assume I'm in trouble.) Of course, humans are much better
at fuzzy logic than COBOL, so it's not like 29 is hardcoded in your head,
but the concept is similar.
(This solution is known as "windowing".)
Oh, and speaking of fuzzy logic:

| (...) Yeah, the windowing/epoching/whatevering isn't a big deal. The thing is, they *hardcoded* the 29. They didn't even make it a constant, defined at the top of the code (or in a copybook). So in some number of years, someone is going to have to (...) (24 years ago, 10-Apr-00, to lugnet.off-topic.geek)

Scary bit of COBOL code one of my co-workers ran across today (he was given the code because it's the closest thing to documentation available for a file he has to deal with): IF FLD_XYZ_YR < 29 THEN FLD_XYZ_YR4 = 2000 + FLD_XYZ_YR4 ELSE (...)
