"global" variables in a babel document...

"global" variables in a babel document...

[Allen S. Rout]

org-version
org "8.2.10"
emacs-version
"24.5.1"


I'm seeing what seems to be some inconsistent treatment of :var header
args.  Or maybe I'm just missing something.   I'm trying to follow:

http://orgmode.org/manual/Header-arguments-in-Org-mode-properties.html#Header-arguments-in-Org-mode-properties

and I find that the local :var works (of course) and the outline level
one also works, but the document-level one does not.

Minimal example, with my results, below.

I'm wondering if I'm thinking about the problem wrong.  What I'm trying
to accomplish is setting, at a document level, a few variables which I
would like to be accessible in every code block in this document.

I know I can set them independently on every block, but that seems
tiresome.

Hello,

It should be #+PROPERTY: header-args :var tsmuser="query"

This works for me, but if you change tsmuser value in session, you have 
to C-c C-c in PROPERTY line, getting "Local setup have been refreshed".

#+PROPERTY: var tsmuser="query"

* foo
  :PROPERTIES:
  :header-args: :var tsmpass="query"
  :END:

#+name: toy
#+begin_src sh :var bloop="foo"
echo sss ${bloop} ddd
echo sss ${tsmpass} ddd
echo sss ${tsmuser} ddd
#+end_src

#+RESULTS: toy
| sss | foo   | ddd |
| sss | query | ddd |
| sss | query | ddd |


Best regards.
