Well, the following one:
\documentclass{article}
\usepackage{etex,m-pictex,m-ch-en}
\begin{document}
\chemical{2H_2,PLUS,O_2,GIVES,2H_2O}
\end{document}
is actually OK!
What is strange is that ppchtex \chemical formulas used to be inserted
between \startchemical and \stopchemical... Moreover, the following:
\documentclass{article}
\usepackage{etex,m-pictex,m-ch-en}
\begin{document}
\startchemical
\chemical[SIX,B,R,RZ][1,2,3,4,5,6]
\stopchemical
\end{document}
works only with \startchemical and \stopchemical.
Are those changes:
1. {}{} rather than [][],
2. pair \startchemical, \stopchemical or not,
3. etc.
documented somewhere?
Thanks.
