Hello,

Sorry for the confusion, I deleted one line more than the result ones.
I guess a new line or a comment or a text is enough to separate the
blocks.

I copied your example without the results, here is the updated
version, and even with a comment between the block produces the same
error `(error "Reference `pid-result' not found in this buffer")'
after calling `org-babel-execute-buffer'

#+NAME: pid
#+BEGIN_SRC shell :results value :cache no
printf '%s' "${$}"
#+END_SRC

#+NAME: pid-result
#+RESULTS: pid

# Some comment is required here to separate blocks, but it does not
# work either

#+NAME: echo-pid
#+BEGIN_SRC shell :var DATA=pid-result :results value
printf '%s' "${DATA}"
#+END_SRC

#+RESULTS: echo-pid

Do I am missing something else?  Thanks again for your assistance.
Daniele
