Thank you very much for this precision, Wolfgang. I tried with two variables and it works with this syntax :

\startuniqueMPgraphic{polygoneregulier} numeric u ; u:=\MPvar{unite}*cm ; numeric n ; n:=\MPvar{sides}; rest of the code \stopuniqueMPgraphic

\define[2]\polyreg {\setupMPvariables[polygoneregulier][unite,sides] \uniqueMPgraphic{polygoneregulier}{sides=#1,unite=#2}}

You can define the command as

\define[2]\polyreg {\setupMPvariables[polygoneregular][sides=#1,unite=#2]% \uniqueMPgraphic{polygoneregular}}

where the variables are set with the \settupMPvariables command or as

\define[2]\polyreg {\uniqueMPgraphic{polygoneregular}{sides=#1,unite=#2}}

where the variables are set in the optional argument for \uniqueMPgraphic.

...

\starttext %\uniqueMPgraphic{polygoneregulier}{unite=2,sides=4} \polyreg{6}{0.5} \stoptext

I did not find any détails on \MPvar et \setupMPvariables on the wiki, however

Both commands are mentioned in the metafun [1] manual.

Thank you Wolfgang for the correction of the syntax. I bought the Metafun manual and began to work with it. Great ! Roland
