In September, Planet Mainframe pays tribute to the programming language that has formed the backbone of many mission-critical workloads — COBOL. Considered by some to be a relic of early computing, COBOL continues to play a vital (if often overlooked) role in the digital infrastructure we rely on. (Did you catch the article on COBOL origins before Grace Hopper?)

From its Cold War origins to its presence in cloud modernization efforts, COBOL has defied repeated predictions of its demise. Why has this language endured for over six decades? What makes it so indispensable to mainframe environments and the industries that depend on them?
