AW: PPCHTeX Bug?

[Tom.G.Meyer@t-online.de (Thomas Meyer)]

Hello, 

I am new here in this list and I am the one who has the problems with
ppchtex.
At first I have to thank Hraban and Tobias for their committed help!
Under LaTeX I tried the downloaded version of ppchtex.tex from
pragma-ade.nl. I got only the lines for the bonds between the atoms, no
letters for the atomic symbols. And I got the error message Tobias and
Hraban reported.
Tobias' version of ppchtex.tex works fine!
The downloaded version works fine only under ConTeXt not under LaTeX.
Is there a bug? Or am I to stupid?

Another question:
Is it possible to create seven-membered ring-systems with ppchtex? I never
found something in the manual about it.

Greetings 

Thomas

Dear readers,
the code in question was the following:

--------------------------

\documentclass{article}
\usepackage{etex}
%\usepackage{pstricks,pstcol,pst-plot}
\usepackage{m-pictex,color}
\usepackage{m-ch-de}
 
\begin{document}
 
% C3-Aldose, Bindungen der Aldehydgruppe rot \startchemical
  {\color{red}{\chemie[SIX,SB2,DB3]}}%
  \chemie[SIX,Z234,SUB2,ONE,Z015,SB1,SB3,SB5,SB7,%
          MOV3,Z0][H,C,O,C,OH,H,\SL{CH_2OH}]
\stopchemie
 
% C3-Aldose, Atome der Aldehydgruppe rot \startchemical
  \chemie[SIX,SB2,DB3]%
  {\color{red}{\chemie[SIX,Z234][H,C,O]}}%
  \chemie[SIX,SUB2,ONE,Z015,SB1,SB3,SB5,SB7,%
          MOV3,Z0][C,OH,H,\SL{CH_2OH}]
\stopchemie

Perhaps this helps to solve this problem with PPCHTeX.

Yours sincerely
