The language that Refuses to Die

Tutorials – COBOL

Despite being more than half a century old, COBOL is still in use. Explore this fascinating old-school language and see how it ticks.

New programming languages pop up all the time. In recent years, there's been plenty of hype around Rust, Go, Swift, Clojure, and many others – and often for good reason. These languages have their own plus points and useful features, and many of them are maturing well. Despite hyperbolic claims from certain overzealous fans, however, none of these languages are going to replace C, C++, or Java completely any time soon. Sure, those languages are old and have their limitations, but they're extremely well established, and rewriting large codebases in the current hot language du jour is a mammoth task.

Although C dates back to the early 1970s, there's an even older language that's still in use – albeit to a much lesser extent. COBOL, the common business-oriented language, was created in 1959 by the US Department of Defense (Figure 1) as a portable language that could be used to process data across many different machines and architectures. The language was standardized a few years later, although there are many different dialects. The most recent update to the language specification was COBOL 2014.

    Of all the strange news this month, the one item that really caught my eye was the announcement of IBM's COBOL for Linux 1.1 compiler. I guess most of us are aware that millions of lines of business software around the world are still written in COBOL, and for that reason, old-school COBOL programmers still have work. But think about this for a minute: COBOL has existed for 62 years, the x86 architecture has been around for 43 years, and Linux has been with us for 30 years.
