I use properties for this, as in:
#+begin_src org
,#+property: version 2.0.5
,#+header: :var version=(esf/get-parameter "benzenefeed")
[...]
,#+begin_src somelanguage
[... code that uses version ...]
,#+end_src
#+end_src
where
#+begin_src emacs-lisp
(defun esf/get-parameter (p)
(let ((value (org-entry-get (point) p 'inherit)))
(message "parameter %s value obtained %s" p value)
(if value
(if (string-match-p "^[-+ ]*[[:digit:].]+$" value)
(string-to-number value)
value)
(error "Property parameter \"%s\" not known." p))))
#+end_src
