Multiple calc commands with orgbabel

[pietru]

Have been trying to execute multiple calc commands, but when I evaluate the calc
expressions, I get just one result.

--------

This does not work

#+begin_src calc
fsolve(x*2+x=4,x)
fsolve([x + y = a, x - y = b],[x,y])
#+end_src

--------

But this works

#+begin_src calc
fsolve(x*2+x=4,x)
#+end_src

#+begin_src calc
fsolve([x + y = a, x - y = b],[x,y])
#+end_src>
