The issue probably needs to be solved, but I happily use Taco's macro for that purpose (works better in titles). See \molecule on http://wiki.contextgarden.net/Chemistry. Mojca

Hello Mojca,
did you try it? Here, I get this error:
I didn't claim that it works in mkiv, I still mostly use mkii (except for non-trivial documents).

Interesting - here it works, but \molecule{A_2} only produces lowered 2, while A is lost.

Ok, I admit that I'm not up to date: TeXExec | context source date: 2008.01.28 21:28 This is LuaTeX, Version snapshot-0.20.2-2008012412 Nevertheless, thanks for the hint to \molecule, it can always be useful with MKII. Cheers, Peter -- http://pmrb.free.fr/contact/

Hello,
The following test-file produces an error:
% engine=luatex \usemodule[chemic] \starttext \chemical{CO_2} \stoptext
This is tooo long. \usemodule[chemic] is enough to produce the error with mkiv. Replace the following lines in m-chemic \ifx\beginpicture\undefined \let\normalgrid\grid \let\normalaxis\axis \input pictex.tex \relax \let\pictexgrid\grid \let\pictexaxis\axis \let\grid\normalgrid \let\axis\normalaxis \fi with \ifx\beginpicture\undefined \let\beginpicture\relax \fi and the module works.

and the module works.
Thanks! I hope, there are no side-effects and the patch could be applied to the distribution! Cheers, Peter -- http://pmrb.free.fr/contact/
