Simply make a copy of your file then run from the MapBasicWindow :
update your_copy set obj=createpoint(centroidx(obj),centroidy(obj))
Make sure that you are working in the proper coordsys by running before
set coordsys table your_copy
I hope I am not too late!
Good luck

Subject: MI Batch - Polygons to centroids
Hi everyone,
I want to transform a MapInfo file which contain 12 000 of polygones
(buildings)
in a file which would include only the centroids of theses polygons
(points).
Do you know if there is a macro which could do that kind of action?
thanks a lot,
Rodolphe
