Hi Kazuhiko,
If CentroidX/Y do not work have you tried ObjectGeography - see below.
****************************************************************************
*****
'*** INCLUDES ***
Include "mapbasic.def"
Declare Sub Main
Sub Main
Dim snLoop As SmallInt
Dim x, y as Float
For snLoop = 1 to TableInfo(TEST, TAB_INFO_NROWS)
Fetch Rec snLoop from TEST
x = ObjectGeography(TEST.obj, OBJ_GEO_POINTX)
y = ObjectGeography(TEST.obj, OBJ_GEO_POINTY)
Print x + " " + y
Next
End Sub
****************************************************************************

Hope this helps,
Mark Crompton

Subject: MI How to extract cursor location from point objects
Hi People outhere,
Does anyone know how to pick up cursor locations from point objects?
I digitized tidal chart on paper as point objects and tried to pick up
their cursor locations with CentroidX and CentroidY, Table > Update
Column.
Location X is not CentroidX. Location Y is not CentoroidY either.
So I made a non smart temporary sulution to adjust Centroid to Location
as below.
Location X ....111189*CentroidX (R^2=1)
Location Y ....111192*CentroidY (R^2=1)
CentroidX LocationX CentoroidY LocationY

I suppose someone knows a smarter and direct solution. Please tell me
how to do it.
One of our major islands, Kyushu was seriously damaged by high sea level
of a typhoon on Sept. 24.
It was at high tide of spring tide and more than twenty aged people in a
small town were killed. No warning system was working for them. Now
local people are measuring tide with an old fashoned analog tide meter
Thanks in advance.
