The creation of FORTRAN and early compilers set the stage to change computing forever. However, they were just the start of a much longer process. Just like a spoken language, programming languages have morphed and changed over time. Today we are looking at an interesting case of this slow evolution. JOVIAL was developed during the Cold War for use in the US Military, and it's been in constant small-scale use ever since. It's story gives us a wonderful insight into how programming language change over time, and why some stick around while others die out.
