Cobol is the opposite of a modern computer langauge, in some ways. But it is the language that a lot of business systems are written in, so chances are you “use” Cobol almost as much as you “use” Linux, even if you never heard of either.
COBOL is used to power almost all global ATM transactions and runs almost three quarters of the world’s business applications. It helps book hundreds of holidays every single day.
And, according to enterprise application management company, Micro Focus, more than 200 billion lines of COBOL code in existence, with hundreds more being created every single day. And a COBOL programming gig is considered to be one of the safest jobs in IT.
