Now that there’s an interest in #COBOL programs, I have to say that COBOL doesn’t deserve the bad reputation it had in the geek community. There are much worse old programming languages, like MUMPS: https://en.wikipedia.org/wiki/MUMPS 

If you’ve heard of Epic EMR (electronic medical records), it’s based at its core on MUMPS. Unlike COBOL, which is known for being verbose and English-like, MUMPS is known for being cryptic, abbreviated, uncommented, and confusing. https://www.healthitoutcomes.com/doc/is-epic-future-proof-0001
