Re: if/else execution in elisp

Thanks for the vote of confidence.  I was starting to doubt reality.  
Here's the bigger fragment:

(defun testo-func ()
  (setq 
   zlist '(2 65535 3)                   
   firsto (car zlist)
   segundo (car (cdr zlist))
   thirdo (cdr (cdr zlist)))

  (if (> segundo 44671)
      (setq firsto (+ 2 firsto)  segundo (- 44672 segundo))
    (setq firsto (+ 1 firsto) segundo (+ 20864 segundo))
    )
  (list firsto segundo thirdo)
  )

When I evaluate (test-func), I want to get (4 20863 3), but I'm getting
instead (4 -20863 (3)).  The hilarious part is that testo-func works 
just fine for a lot of setq'd values.  


I'm about to die laughing.  Please help it stop.

= It looks correct to me.  What's the problem you're having?
