I would like to pass the lua table keys and values to metapost. In the keys i have information about the paths names and in the values i have information about the label that should be draw in the center of each path (unitsquare). 

In my code (see attach) the table in question is "weekdays_number_and_name". 

I know that is possible to pass a array from metapost to lua. Is the reverse possible?

thanks in advance
