What about :

#+NAME var-as-literal-block
#+BEGIN_EXAMPLE
99
#+END_EXAMPLE


#+begin_src ...  :var TheVar=var-as-literal-block
...using TheVar in code
#+end_src

----------------------------
I would prefer using Macros in this case :

#+MACRO: TheVar 99

#+begin_src ... :var TheVar={{{TheVar}}}
...using TheVar in code
#+end_src


But looks like that macros do not expand in src_block header arguments.

Regards, Olaf
