Cobol Skills Are In Demand! COBOL Remains in High Demand* Industries that rely heavily on mainframes also depend on apps written in COBOL, the venerable mainframe programming language. Almost no one learns COBOL these days. You’d be hard-pressed to find a college computer science program that includes instruction in it. Yet the fact is that COBOL skills are still in demand. And precisely because younger COBOL programmers are in short supply, businesses that depend on COBOL are willing to pay top dollar for programmers who can provide COBOL expertise. *Enterprise Systems Media, 5 Things Everyone Should Know About Mainframes, by Christopher Tozzi on January 2 nd 3/8/2021 IT'S BEST KEPT SECRET 31
