I never used FORTRAN outside college. Nor COBOL, thank god. COBOL class almost had me change my major to Astronomy or Psychology

IRL I coded in whatever the project needed. Lately I fool around with Python, but that's manager level coding. Basically crap coding quality.

True story my company hired a contractor once to help us through a project. He'd never coded C, which seemed problematic since it was a C project. He asked to borrow my K&R C bible one day, and took it home. The next day he came in, pointed to some esoteric part of the language and asked me to explain. He was cranking out running code that very day. JFC that intimidated the hell out of me. Then I was reviewing his code and realized he had no error handling. I asked what would happen if the user entered an invalid value, like zero. He asked, "why would they do that?" Oh my. I was no longer intimidated.
