I am sure that this is a trivially simple issue that I've simply overlooked in the manual, but by God, I've been studiously overlooking it for about an hour...
I simply print a few things...
#+BEGIN_SRC emacs-lisp :export output
(let (
(dog (sqrt 2))
(cat 7)
)
(print (format "%s %f" "Dog: " (eval dog)))
(print (format "%s %d" "Cat: " (eval cat)) nil)
(print "Fish.")
)
#+END_SRC
#+results:
: Fish.
Only the last value ever survives the printing process. One line attempts to print to standard out without specification, and the other names the stream specifically, but in all cases, only the last message ever seems to survive. It is as if all messages are directed to the minibuffer, happily clobbering previous output like a sequence of baby seals, and then that minibuffer is reported as the output stream.
Is there some way to allow for all printed output to survive?

Hi Matthew,
You're not missing anything obvious, there are two points which are
keeping this from succeeding.
First, emacs-lisp did not support the ":results output", however I've
just pushed up a patch which adds this support to emacs-lisp code
blocks.
Second, you have ":export output" below, when you should have ":results
output", and if you do want to change export options the header argument
is ":exports" (plural) not ":export". I really need to implement some
sort of highlighting to catch these small header-argument errors as
they're extremely common.
With the latest Org-mode the following should work.
#+begin_src emacs-lisp :results output
(let ((dog (sqrt 2))
(cat 7))
(print (format "%s %f" "Dog: " (eval dog)))
(print (format "%s %d" "Cat: " (eval cat)) nil)
(print "Fish."))
#+end_src
#+results:
:
: "Dog: 1.414214"
:
: "Cat: 7"
:
: "Fish."
Although I'd recommend returning the value as a list
#+begin_src emacs-lisp
(let ((dog (sqrt 2))
(cat 7))
`((dog ,dog)
(cat ,cat)
(fish)))
#+end_src
#+results:
| dog | 1.4142135623730951 |
| cat | 7 |
| fish | |
Cheers -- Eric
