whoa, how do you mispell your own name??? (the code and the submission have different spellings of "fras(e)(o)r".)

BEGIN COBOL-CURSING SECTION.

And now all you people know why, in my waking hours, in my sleep, in my dreams, I curse COBOL and everything it stands for.

I hate COBOL. This language sucks. It can die a terrible, terrible death.

 Louis said on 07/19/05 11:13:02

And that, my friends, Is why I'm sooo happy that
I don't have to work in COBOL anymore ....

It's supposed to be bottles of beer ON the wall, not IN the wall.

 Don said on 04/26/08 00:28:42

Not as terse as it could be. But nowhere near as verbose as the Java and C programs that do the same thing.
