Xu,
1. Select the line object
2. Open the Mapbasic window: Options > Show MapBasic Window
3. For Start point X, type in: print ObjectNodeX(selection.obj,1,1)
4. For Start point Y, type in: print ObjectNodeY(selection.obj,1,1)
5. For end point X, type in:
print
objectNodeX(selection.obj,1,objectinfo(selection.obj,20))
6. For end point Y, type in:
print
ObjectNodeY(selection.obj,1,objectinfo(selection.obj,20))
....
ObjectNodeX Returns the x-coordinate of a specific node in a region or
polyline object.
Syntax: ObjectNodeX( object , polygon_num , node_num )
....
Hope this helps,
