The following MB code uses an ever increasing circular buffer to look for 5
nearest objects in BaseTable. BaseTable is a non-earth projection in metres.
If the buffer centroid is (5,20) it works fine. If its (4.5,19.5) the search
doesnt find any objects and gets stuck in a continuous loop. Any ideas
why?!!
Many thanks..

Set Coordsys Table BaseTable
Set distance units "m"
Create Point (4.5,19.5)
o_pnt = CreatePoint(4.5,19.5)
f_bandopt = 5
Do
o_buffer = Buffer(CreatePoint(4.5,19.5), 20, f_bandopt, "m")
Select centroidx(obj), centroidy(obj)
from BaseTable
where (o_buffer contains object)
into SearchResults
i_foundpnts = SelectionInfo(SEL_INFO_NROWS)
f_bandopt = f_bandopt * 2
Loop until i_foundpnts >= 5
