It works! The ans variable is the secret! Thanks a lot. I suggest org should provide some examples in its user's guide, not only on the topic of Babel but also Table, Hyperlink, Picture, and etc. ----------------------------- etimecow...@gmail.com _.,----,._ .:' `:. .' `. .' `. : : ` .'`':'`'`/ ' `. \ | / ,' \ \ | / / `\_..,,.._/' {`'-,_`'-} {`'-,_`'-} {`'-,_`'-} `YXXXXY' ~^^~ _______________________________________________ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.
