Aha -- you have to use the :var syntax on the begin_src line, not the params-in-parens syntax on the name line. Your version works:
#+name: example-block #+begin_src sh :var input="" echo "input is $input" #+end_src but this doesn't: #+name: example-block(input="") #+begin_src sh echo "input is $input" #+end_src The doc seems to say it should work the same, in http://orgmode.org/manual/var.html (see "Alternate Argument Syntax").
