Question: =3D:results org replace=3D (instead of =3D:results org=3D) is nec=
essary if
we wanna see the results expanded in the Org buffer, on key =3DC-c C-v C-e=
=3D.
Why?

Trying to build on the route you mention, I come up with different solution=
s,
such as:

--8<---------------cut here---------------start------------->8---
#+TITLE:     Org-isodoc
#+AUTHOR:    Seb Vauban

Asking for Org results, as you mentioned, made me dream about a direct expo=
rt
to PDF on =3DC-c C-v C-e=3D. However, when the Org results block =3Dletter=
=3D is
surrounded by LaTeX code, items and tables aren't translated anymore to the=
ir
LaTeX counterparts.

OK, even if it doe, I still have a couple of problems to resolve:

- How to avoid generating the title of the exported headline (=3D* Results=
=3D)?
- How to impose my =3Ddocumentclass isodoc=3D instead of =3Darticle=3D?

and maybe more.

Then, if I understand correctly, the only fallback is the tangling solution:

--8<---------------cut here---------------start------------->8---
* Letter
  :PROPERTIES:
  :ID:       02360e5c-8f76-4e6d-a98f-b8c5fa2a3da4
  :END:

#+begin_src latex :noweb yes :tangle yes
\documentclass[11pt]{isodoc}

\usepackage[T1]{fontenc}

\setupdocument{

    subject =3D {Tough to understand what to do...},
    opening =3D {Hi},
    closing =3D {Best}
}

\begin{document}

}

\begin{document}
\letter{%

\begin{itemize}
\item one

\end{itemize}

and a small table:


\begin{center}
\begin{tabular}{ll}

\end{tabular}
\end{center}



Not more.

}
\end{document}
#+END_LaTeX
--8<---------------cut here---------------end--------------->8---

Here, the above results is perfectly translated into LaTeX. But trying to
export this buffer raises the =3DArgs out of range: 0, 0=3D error.

The solution is to tangle it, and launch pdflatex on the tangled file.

Questions:

- Is the above overview right, or am I *still* missing things?

- Couldn't =3DC-c C-v C-e=3D tangle to files, when the =3Dtangle=3D paramet=
er is
  present?  FYI, I've lost some amount of time (won't tell you how much, I'm
  ashamed) thinking that the tangling process did not work anymore on my
  machine, because I was expecting it on =3DC-c C-v C-e=3D. At my discharge=
, I
  only used tangling once, a couple of months ago, but...

  ... and I think I already had once that request in mind, maybe even asked=
 on
  the list.

Idealistic goal that I have in mind (so that I share upfront which directio=
ns
I would enjoy to be able to follow):

- be able to produce =3Disodoc=3D letter in PDF just by =3DC-c C-v C-e=3D

- next step: be able to produce /mail merge/ ("publiposting"), having in Org
  the list of recipients and the letter's contents -- both in one unique Org
  file --, and producing all the letters at once (in one PDF), just by =3DC=
-c
  C-v C-e=3D...

Thanks for your help (past, present... and future)!

Best regards,
  Seb
