Hi Herb,

The following org-mode file and minimal elisp file can be used to print
the results of evaluating a code block from a batch Emacs session (note
this is using Emacs24, so Org-mode/Babel do not need to be explicitly
loaded).

I used the following command line
: emacs --batch -l run-code.el 2> /dev/null

And the following two files.

(let ((org-confirm-babel-evaluate nil))
  (progn (find-file "short-code.org")
         (org-babel-next-src-block)
         (print (org-babel-execute-src-block))))

  print "bye"
#+end_src

#+results:

: bye
