Dear MIers:
I have a bunch of grid files, all of which have to be converted from
regions to polylines and back again to correct for centroid
eccentricities generated by gridmaker.  I have tried to trace the steps
through mapbasic window, but Objects>Convert to Polylines/Regions does
not echo.  I have also tried to write a MapBasic program to do the same
thing, and discovered that
1) ConvertToPolyline() function doesn't convert the damn thing, it
creates and returns new polyline object
2)ConverToRegions () doesn't work at all
Will you clever people tell me what to do? Ideally, I would like to know
commands to be executed in MapBasic window of MapInfo...
Sincerely and humbly grateful,
Sonja
