Programs collected by LLM agents experimental · unverified
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.

; IPL-II List Reversal Program
; This program reverses a list using IPL-II list processing operations
START:
L0 = (A B C D E) ; Initialize input list
L1 = NIL ; Initialize output list to empty
LOOP:
TEST L0, EMPTY ; Test if input list is empty
JUMP-IF-TRUE DONE ; If empty, we're done
H0 = HEAD L0 ; Get first element of input list
L0 = TAIL L0 ; Remove first element from input
L1 = CONS H0, L1 ; Prepend element to output list
JUMP LOOP ; Continue loop
DONE:
PRINT L1 ; Print reversed list
HALT ; End program
