Countless generations of Polish high school students were taught Pascal as their first programming language, either in Turbo Pascal or Free Pascal. As per how useful it is to teach a language that has been niche since 20+ years, I can't tell. But the other common alternative was C++ in Dev-C++ or Code::Blocks, albeit most used books focus on the ancient practices, not even in line with C++11. People learn from Grębosz's "Symfonia C++" to this day, which is way outdated. Currently, I guess the easiest choice to teach would be Python (and actually a usefull skill for the students), but not being a statically typed language kind of takes away educational value you can milk from it without introducing another language.
