The comments in ob-lisp.el makes it clear that it is not complete support yet. It appears for example that you can only evaluate one lisp form per code block. Here is an example. * First, let's try in emacs lisp The following works how I would expect. The value in the results block is the value of the last expression in the code block. #+begin_src emacs-lisp (defvar test1 "test1 value") (defvar test2 "test2 value") test2 #+end_src #+results: : test2 value * Now, let's try common lisp First, we need to start up a SLIME session, with M-x slime. This assumes you have SLIME set up correctly. I am using SBCL as my CL environment in this example. #+begin_src lisp :session (defvar test1 "test1 value") (defvar test2 "test2 value") test2 #+end_src #+results: : TEST1 You see the result in the buffer is the value of the first form, and if I go into the inferior-lisp buffer, test2 is not bound to any value. If I evaluate the CL code block above without the :session argument, I get an error in the *Org-Babel Error Output* buffer. Looking at the code in ob-lisp.el, I think I see why this is happening, but don't know enough about SLIME yet to make it work. It seems that line that calls =eval-slime= would need to be changed to =eval-slime-buffer= after dumping the code block into a temporary buffer. However, that didn't quite work since that function (=slime-eval-buffer=) doesn't appear to actually return the final value. So, I write this in case this is an easy fix for someone with more knowledge of SLIME, and to confirm that this is indeed the current behavior that others see. I will continue to investigate a solution. Thanks, --Erik
