Hello,

thanks to contributors of this list I was able to use ppchtex with
LaTeX when I encountered a "\writestatus: Undefined control sequence"
problem:

http://www.ntg.nl/pipermail/ntg-context/2009/044672.html

Everything went well (though I have a little use of ppchtex) but, as I
tried it some days ago, I was facing another trouble pointed out by the
following MCE:

\listfiles{}
\documentclass{article}
\usepackage{etex,m-pictex,m-ch-en}
\begin{document}
\startchemical
\chemical{2H_2,PLUS,O_2,GIVES,2H_2O}
\stopchemical
\end{document}

The error is:

! Undefined control sequence.
\dodogetgroupargument ->\normalifx
                                   \nextargument \bgroup \endrobusttest
\nos... l.6 \chemical{
              2H_2,PLUS,O_2,GIVES,2H_2O}
?

Here is my files list:

 *File List*
 article.cls    2007/10/19 v1.4h Standard LaTeX document class
  size10.clo    2007/10/19 v1.4h Standard LaTeX file (size option)
    etex.sty    1998/03/26 v2.0 eTeX basic definition package (PEB)
m-pictex.sty    2004/07/30 package wrapper for m-pictex.tex
m-pictex.tex
 m-ch-en.sty    2004/07/30 package wrapper for m-ch-en.tex
 m-ch-en.tex

It seems that mkiv seems still not ok with my up-to-date TeX Live 2009,
as:

$ more test-context-minimal.tex
\starttext
Hello World!
\stoptext

$ context test-context-minimal.tex
MTXrun | unknown script 'context.lua' or 'mtx-context.lua'

But mkii is ok (tested with `texexec test-context-minimal.tex`). And,
with mkii, the following ppchtex MCE is OK:

\usemodule[pictex,chemic]
\starttext
\startchemical
 \chemical[SIX,B,R,RZ][1,2,3,4,5,6]
\stopchemical
\stoptext

Thanks in advance for any hint...
