Thank you Hans, this is exactly what I need.

I will wikify the examples.

Kind regards,

You need to compensate these solutions by "wikifying" them:

\starttext

\startuseMPgraphic{whatever}{s::mode}

     u := 2cm ;

     draw unitsquare scaled u ;

     drawdblarrow (0,-0.2u)..(u,-0.2u) ;

     drawdblarrow (1.2u, 0)..(1.2u, u) ;

     if "\MPvar{mode}" = "en" :

         label("e", (0.5u,-0.4u)) ;

         label("n", (1.6u, 0.5u)) ;

     else :

         label("n", (0.5u,-0.4u)) ;

         label("l", (1.6u, 0.5u)) ;

     fi ;

\stopuseMPgraphic

\useMPgraphic{whatever}{mode=en} \blank

\useMPgraphic{whatever}{mode=nl} \blank

\startuseMPgraphic{whatever}

     u := 2cm ;

     draw unitsquare scaled u ;

     drawdblarrow (0,-0.2u)..(u,-0.2u) ;

     drawdblarrow (1.2u, 0)..(1.2u, u) ;

     if texmode("en") :

         label("e", (0.5u,-0.4u)) ;

         label("n", (1.6u, 0.5u)) ;

     else :

         label("n", (0.5u,-0.4u)) ;

         label("l", (1.6u, 0.5u)) ;

     fi ;

\stopuseMPgraphic

{ \enablemode[en] \useMPgraphic{whatever} } \blank

{                 \useMPgraphic{whatever} } \blank

\stoptext
