Thanks.

Interesting.  If I evaluate org-export-blocks-preprocess, all looks well
and the resulting buffer exports correctly with org-export-dispatch.
The evaluated results of the #+call: lines are present in the
preprocessed buffer, and the #+call: lines themselves are gone.

Apparently, something else happens when the original buffer is exported
with org-export-dispatch. This route appears to ignore the evaluated
results of the #+call: lines and instead uses the results of a new call.
This was failing for me because I'd set :eval no-export on the source
code blocks after I'd evaluated the #+call: lines in the buffer,
thinking that the exporter would find the results and use them.

Thanks for your help, and apologies for the noisy posts.

All the best,
Tom
