I worked for a health insurance claims benefit management software company whose flagship was written in a language called DB/C (random bonus, the two co-owners of the company felt that two spaces for a tab stop was too small, four too large, so had standardized on a three space tab). DB/C (or Databus) is a COBOL-esque language (https://en.wikipedia.org/wiki/Programming_Language_for_Business https://en.wikipedia.org/wiki/Programming_Language_for_Busin...). Over time, TCP/IP, sockets support had been bolted on, with varying degrees of rigidity to spec (and a whole ton of unimplemented "we don't need THAT" stuff). But the prize for eyebleeding was the co-owner who had a megalomaniac (he could be heard, and I quote word for word, saying things like "People are idiots, I don't know why they would write [software X] that way. I can do it in a weekend" (and he would do "it", too, in 60 hour long benders. But not well. And with a whole bunch of arbitrary bullshit that you'd expect), masochistic, NIH obsession. He wrote a fully functional XSL parser and interpreter. In a COBOL-esque language. And while functional, oh boy, you probably saw few things uglier in your life.
