I see I have a multiplication error below.... but it's on the low
side. Make it 6 TRILLION lines. Anyway - I don't think each COBOL
programmer is solely responsible for a million lines of code, but it
could be an interesting way to figure it out. Each could easily be
responsible for 100,000 lines and if there are 6 million of us (I bet
there's more) that's still hundreds of billions of lines of code.
