"Imminent Death Of Cobol Predicted. Again."

When the sun finally expands into a supergiant in five billion years,
destroying the earth, the last survivors to die will be COBOL-programming
cockroaches and Keith Richards.

If PIC is so great, why do no other languages have it?

That's a serious question, not a rhetorical question.

Indeed. What's your point? Because that sounds awfully like an ad hominem
fallacy. Dijkstra was arrogant, therefore he must be wrong.

"Violent"?

Are you one of those people who think that calling a person an idiot is
morally indistinguishable from beating them into a coma?

"Sticks and stones will break my bones, but that's nothing to the harm
caused by a few mean words."
