"As old as COBOL is (60 years old prog. language), it is still heavily used in information management systems and pretty much anywhere there’s an IBM mainframe around. Three years ago Thomson Reuters reported that COBOL is used in 43% of banking systems, is behind 80% of in-person financial transactions and 95% of times an ATM card is used. They also reported 100s of billions of lines of running COBOL.
COBOL can now be used to write code for Cloudflare’s serverless platform Workers."
