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.

⍝ Quicksort in ngn/apl
qsort←{
  1≥≢⍵:⍵
  pivot←⍵[⌊2÷⍨≢⍵]
  (∇⍵[⍸⍵<pivot]),pivot,(∇⍵[⍸⍵>pivot])
}

⍝ Test with unsorted array
qsort 3 1 4 1 5 9 2 6 5 3 5

⍝ Sum of first 10 integers
+/⍳10

⍝ Outer product: multiplication table
∘.×⍨⍳5
