Technically, it's the output of your first mainframe COBOL program. But, I'm pulling your chain. Congratulations!

I know guy in Winston-Salem, who is not so old, and who is making a fine living as a contractor doing COBOL. Critical business processes, especially in financial area (banks, insurance, brokerage), use COBOL programs written decades ago that need tweeks now and then. As you say, they are not making those mainframe programmers anymore so the demand is there. Definitely not a fad language.

This maybe the opportunity you have sought.

On warning though - COBOL is probably the most OO language of the 1960's. :)
