Lisp simple question

Question

Hi! I have some not understanding actions from gnu clisp Suppose, I have some code like (let ((x "Hi!"))(print x)). If I execute it from console (like, clisp fileName.lisp) I see

Hi!

But, when I execute it from interpreter, I see this text twice. Why?

Help me, please.

Answer 1

The interpreter always outputs the value of the last expression.
print also returns the parameter as a value, "Hi!" in your case.
That's why you see it twice.

(print "Hi!") 

will give the same result.
