In France, we have a tool called WinDev which isn't used very much outside of France. It is a proprietary abomination used to create graphical applications (and with sisters tools WebDev and WinDev mobile for web development and mobile development). It completely locks the programmers into their shitty very closed wall garden (for example, you're completely locked into using their own proprietary version control tool and absolutely cannot use an alternative).
Anyway, the coding in their applications is done with their very own proprietary shitty programming language: WLangage (https://fr.wikipedia.org/wiki/WLangage). This language has the particularity of being available in three localizations: English, French and Chinese. And you can mix all three in the same codebase for some extra fun!
It's not very well known outside of France so it's not very surprising that this language isn't cited on the wikipedia page you linked.
