Here is a minimal example without the vim-typing module.

\setupbodyfont[ss, 14pt]
\setuppapersize[S6][S6]
\def\startC%
   {\bgroup
   \whitespace
   \obeylines
   \ignoreeofs
   \ignorespaces
   \activatespacehandler{yes}
   \def\obeyedline{\par\strut}%
   \strut}

\def\stopC{\egroup}

\starttext
\startC
\stopC
\xypos{XXX}
\startC
bla;
bla;
bla;
\stopC
\startC
bla;
bla;
bla;
\stopC
\startC
bla;
bla;
bla;
bla;
\stopC
\startC
bla;
bla;
bla;
bla;
bla;
\stopC
\stoptext

which gives
