Hi Johannes,

replace the current definition of \zeichenzelle with the following:

\def\zeichenzelle#1%
  {\advance\zeichencolumn\plusone
   \hbox
     {\vtop
        {\hsize\zeichenparameter\c!width
         \normalbaselines
         \zeichenparameter\c!before
         \begstrut
           \dostartattributes{\????ze\number\zeichencolumn}\c!style\c!color
           \zeichenparameter\c!left
             #1
           \zeichenparameter\c!right
           \dostopattributes
         \endstrut
         \zeichenparameter\c!after}}}

\synchronizegrid in \setupzeichen is not neccessary

\setupzeichen
  [\c!textwidth=63.8833mm,
   \c!before=\noindenting, %\synchronizegrid,
   \c!after=, %\synchronizegrid
  ]

add the next two commands to your module

\def\startzeichen{\begingroup\offinterlineskip}
\def\stopzeichen{\endgroup}

a alternative version

%\def\startzeichen{\offinterlineskip}
%\def\stopzeichen{\oninterlineskip}

and put \startzeichen and \stopzeichen before and after your lines
with all \zeichen commands

\startzeichen
\zeichen
...
\zeichen
\stopzeichen

and everything should work as expected

Wolfgang
