I've made a *simple* environment for writing pseudocode in emTeX, which
I thought was pretty near compatible with LaTeX.  In emTeX, the file
compiled nicely, in LaTeX I got this reply:


! Use of \endpseudocode doesn't match its definition.
\end #1->\csname end#1\endcsname \@checkend 
                                            {#1}\if@endpe \global \let \@gte...
l.398 \end{pseudocode}

                      
My document looks like this ([...] means cut-out material):

\documentstyle[emlines2]{artikkel}
% Artikkel is a Norwegian version of Article, which has just some words
% translated.
% emlines2 is needed for special line drawing in emTeX.

% what follows are some simple macros

\newcommand{\preadytabs}
        {
\=012345\=012345\=012345\=012345\=012345\=012345\=   \kill
        }

\newcommand{\pnew}[0]			%/pnew starts a new pseudocode line
        {
        \ifnum \value{pseudoline} >0 \\ \fi
        \addtocounter{pseudoline}{1}
        \>\rm\arabic{pseudoline}\>	% number each line
        }

\newcommand{\pline}[1]			%\pline just outputs its argument
        {#1}

[...]

\newcommand{\pcomm}[1]			%\pcomm outputs a pseudocode comment
        {\pline{$\rhd$\'#1}}


\newenvironment{pseudocode}[1]
        {				% begin
%       \setcounter{pseudotabs}{1}
        \setcounter{pseudoline}{0}
        \begin{tabbing}
        {\large\tt #1}\\		% output algorithm name
        \preadytabs			% set up tab stops
        }
        {				% end
        \end{tabbing}
        }


\begin{document}

[...]

\begin{pseudocode}{pack(inFileName, outFileName)}
        \pnew\pcomm{Open input and output files}
[...]
        \pnew\pcomm{Avslutt}
\end{pseudocode}			% this is line 398, where the error
					% occurs

\begin{pseudocode}
[...etc]

\end{document}


Can anyone explain why LaTeX won't accept this, while emTeX does? 
I will gladly e-mail the tex file to anyone interested in checking it 
out for themselves.
