[O] [babel] using #+call for inline results

[Eric S Fraga]

Hello,

I have been playing with org babel for putting results inline within an
exported latex file.  A simple example is here:

--8<---------------cut here---------------start------------->8---
* testing inline evaluation of babel source blocks
  
  #+srcname: benzene-chlorobenzene-relative-volatility
  #+begin_src octave :exports none :results output raw :var T=25
format bank
pb = 10^(6.89272 - 1203.531/(T+219.888));
pc = 10^(7.10690 - 1500.0  /(T+224.000));
alpha = pb/pc;
disp(alpha)
  #+end_src

  1. The first step is to evaluate the relative volatility at \(T=25 ^{\circ} 
C\): 
     #+call: benzene-chlorobenzene-relative-volatility[:results output 
raw](T=25) :exports results

  2. Compare this to the value we get at 50 \(^{\circ}C\):
     #+call: benzene-chlorobenzene-relative-volatility(T=50) :exports results 

  3. Next we use this value to draw an equilibrium curve.
      
--8<---------------cut here---------------end--------------->8---

If I evaluate the code block, I get what I expect:

,----
|   #+results: benzene-chlorobenzene-relative-volatility
|   7.86
`----

However, when I export the file, the #+call lines get wrapped in a
verbatim environment regardless of what or where I specify for
the :results header arguments.  E.g.:

,----
| \begin{enumerate}
| \item The first step is to evaluate the relative volatility at \(T=25 
^{\circ} C\): 
| 
| 
| \begin{verbatim}
|       7.86
| \end{verbatim}
| 
| \item Compare this to the value we get at 50 \(^{\circ}C\):
| 
| 
| \begin{verbatim}
|       6.32
| \end{verbatim}
`----

What am I doing wrong?  I have tried various permutations of the
placement of the :results header and various options for it but do not
seem to have hit on the right combination.

Ideally, I would like the number to appear completely inline with the
text the precedes and follows the #+call statement.  I would prefer to
not have a new paragraph started, for instance.

On a related note, although the manual seems to indicate that "raw" and
"org" are synonymous, they behave differently when evaluating a code
block with the latter encapsulating the output within #+begin_org
and #+end_org.  The behaviour is fine but maybe the documentation,
assuming I have understand things correctly, should be changed to
reflect the difference in behaviour?

Thanks,
eric
