Okay. I take here the "any advice is appreciated" part. AFAICS at the org babel calc evaluation the last value of the calc stack gets dropped. So your workaround is okay, I think. You can just write any dummy element at the bottom of each block e.g. just 0. No need of duplication. Looks a bit hackish to me but so what? Another approach could be "noweb". Example (you would just evaluate the block at the bottom): --8<---------------cut here---------------start------------->8--- Number of cars (PKW) in germany: #+name: numcars #+begin_src calc :exports both 45e6 #+end_src Yearly mileage in [km/y] #+name: mileage #+begin_src calc :exports both 15000 #+end_src Calculate amount of complete km per year #+begin_src calc :noweb yes <<numcars>> <<mileage>> '* #+end_src --8<---------------cut here---------------end--------------->8--- HTH, -- Marco
