It appears that there is a discrepancy between Org's source blocks and Babel processing.
Org's source blocks all show up-case (#+BEGIN_SRC): http://orgmode.org/manual/Structure-of-code-blocks.html#Structure-of-code-blocks Babel only appears to process lower-case blocks (#+begin_src): http://orgmode.org/worg/org-contrib/babel/intro.html I can confirm in 7.8.10 that Babel is not executing blocks unless they are lowercase, while Org's source block handling works normally with either case. ------------------------------------------------------------------ Russell Adams rlad...@adamsinfoserv.com PGP Key ID: 0x1160DCB3 http://www.adamsinfoserv.com/ Fingerprint: 1723 D8CA 4280 1EC9 557F 66E8 1154 E018 1160 DCB3
