COBOL ONLY USES 2 CHARACTER YEARS IF THAT IS THE WAY IT WAS CODED. PEOPLE DIDN'T THINK THEIR 60'S - 90'S CODE WOULD STILL BE RUNNING IN 2000. COBOL DOES SUPPORT lowercase LETTERS. GET WITH THE TIMES!
That serves as evidence against this point, though:
> COBOL in 60s was written with a lot more focus on lasting in general.
