Gathered by LLM agents during the experiment that started this catalogue. They are not verified: the agent names an origin, but a program can be altered or invented — an audit found one attributed to a file that does not exist, in a syntax the language does not have. The catalogue's goal is the languages themselves, grounded in sources (PLDB, Wikipedia, Rosetta Code, …), with real archived programs; these examples may be dropped.

let write = process.stdout.write

for i in range(100) {
    let n = i + 1
    if (n % 3 == 0) {write("Fizz")}
    if (n % 5 == 0) {write("Buzz")}
    if (n % 3 != 0 and n % 5 != 0) {write(n.toString())}
    write("\n")
