(defun x (a b c)
(let (square (sqrt (- (* b b) (* (* 4 a) c)))) (list square))

Hi,

I'm learning this brilliant language and i'm using lisp-in-a-box. One "problem" i have is when want to save what i write.

Do i really need to create a new file and write the code again in that file? Is there not a more effective way?
