But the following MCE:
\documentclass{article} \usepackage{etex,m-pictex,m-ch-en} \begin{document} \startchemical \chemical[2H_2,PLUS,O_2,GIVES,2H_2O] \stopchemical \end{document}
leads to the messages: [...]
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. -- Denis
