[Gvsig_english] Field calculator::possibility to calculate x/y coordinates?

[Wolfgang Qual]

Hi Antonio, list,
thanks for this idea, Antonio! However, I would prefer to have a script, 
function, button etc. within gvSIG for Shapefiles. At the moment, we do not 
even have a PostGIS-database in our office. Could imagine that it would be a 
very nice example for the create-an-extension-capabilities in gvSIG. Ideas 
are welcome!

Best,
Wolfgang
