Have :var reference a value

Have :var reference a value

I'm playing around with learning racket in an org buffer and I have a bunch
of blocks that look like this

   #+begin_src racket :var value="abbracadaabra"
   ...do stuff with value...
   #+end_src


   #+begin_src racket :var value="abbracadaabra"
   ...do other stuff with value...
   #+end_src

Is there a way to move the "abbracadaabra" string into a single location so
that I can just pull the var from that? I know I can put it in a table or a
list, but how about into a single value?

Make it a property:

#+PROPERTY: magic abbracadabra

#+begin_src emacs-lisp :var value=(org-entry-get (point) "magic" t)
value
#+end_src

#+RESULTS:
: abbracadabra


When you add/change a  property like this be sure to update (C-c C-c on the PROPERTY line or save, close, open the file).

For a long string, you might put it in a src block and then use :var value=block-name() to get it.

HTH,
