I wrote the manual for the Navy language SPL/I, Signal Processing Language I. That was the late 70’s when government overseerers showed up with bare chests to their waist and gold chains, bragging about their employment level. That’s how I got into language design. I’d be told of one language change and be able to make all the parallel changes to keep the language consistent. Didn’t realize I knew the language, just knew I knew my book cold. Fun days. Was also on the program committee for History of Programming Languages run by Jean Sammet. She was another big Star Trek fan.
Ada is a pretty good language. PL/SQL in Oracle databases is modeled after it.
