Comment So learn COBOL (Score 2) 99
"...even though there are very few Cobol-literate coders available to maintain them."
I had a programming opportunity that involved programming in RPG on an IBM platform. I had zero experience with the language or platform, but wanted the job, so I did a very deep dive into all things RPG and IBM, nailed the interview, got hired, and have been modifying and developing new programs for short of two years. It was a wonderful change from 35+ years as an IT generalist, and I haven't looked back.
