I've been writing a 'hello world' program which consists of a function that returns T if the given parameter is prime or else it returns NIL; the only thing is, it doesn't work.
Scrub that, I've just fixed it:
==================================== (defun prime-rfunc (x iterator) (if (= x iterator) (not ()) (if (= 0 (mod x iterator)) () (prime-rfunc x (1+ iterator))))) (defun prime (x) (prime-rfunc x 2)) (print (prime 1471)) ====================================
