Well, what I was using was called Burroughs COBOL. I was using it on minicomputers, but it was basically the same COBOL that ran on the big Burroughs mainframes. Mainframes needed to maintain backward compatibility, so I guess the COBOL I was using was 1st-generation.

I gave up COBOL before I ever encountered any Structured COBOL. Around that time I performed psychological repression of all memory I had of the language, or even that I'd used it.

It has taken years of programming-language therapy for me to start to recover these memories.
