[Orgmode] [Babel] Output of multiple variables from octave source

[RCY]

Hi,
 I would like to output multiple variables from an octave program. When I evaluate:

      #+srcname: test.m
      #+begin_src octave
      clear variables
      x=5.1;
      y=3*x;
      sprintf('x=%.1f',x)
      sprintf('y=%.1f',y)
      #+end_src

I get       
      #+results: test.m
      : y=15.3

 Is there a way to get multiple variables output, other than something like:
#+srcname: test.m
      #+begin_src octave
      clear variables
      x=5.1;
      y=3*x;
      sprintf('x=%.1f,\n y=%.1f',x,y)
      #+end_src
      
      #+results: test.m
      : x=5.1, y=15.3
      
which starts to get unwieldy for a larger number of variables.

I am using the org-mode from git in Emacs 23.1.

Thanks for any help.
