(REPL) A programming structure within LISP which repeatedly reads a form from the user, evaluates it, and displays the result. A read-eval-print loop forms the basis of the Top-Levelshell that programmers of the LISP family of languages interact with. In many dialects of LISP a very simple REPL could be implemented as: (loop (print (eval (read)))). (2003-06-23)
