Re: OMG - COBOL
Upvoted for the recognition.
I would have been one of those who wouldn't admit to knowing anything at all about COBOL.
Which wasn't entirely true, COBOL did take up one stream of lectures ("Business Computing") for a semester of my 1970s post-grad CS course, and taught me everything I'd ever need to know about it.
Which was that I never wanted to see it again, and therefore should not mention it in polite company, or on my CV.
