I want the following:

(defun foo
  (if (bar)
      (if (foobar)
          (print result)
        nil)
    (barfoo)

This should work as follows: If bar, then: return result if foobar, and nil if not foobar. If not bar, then return barfoo.

How do I have to modify my code for this?

Looks right to me, heres a slight simplification.

Code: Select all

(defun foo
  (if (bar)
    (when (foobar) result)
    (barfoo))

If you want the result that foobar is generating (and foobar returns NIL if no result)...

Code: Select all

(defun foo (if (bar) (foobar) (barfoo)))
