what about just returning the coordinates of the object rather than the
object itself, then evaluating those coordinates to determine whether they
lie within a specified zone?
i can't say much about your "specified date" or "certain fields" as i don't
know where this data is coming from, ie whether it's on a form somewhere or
PART of the selected object itself.
so, getting the coordinates (i werk in VBA, but the code should be pretty
close)
#############################
dim X as Float
dim Y as Float
dim NumSel as Long
NumSel = selectioninfo(3)
If NumSel > 1 Then
msgBox "Please select only ONE object."
ElseIf NumSel < 1 Then
msgBox "Please select an object."
ElseIf NumSel = 1 Then
X = objectgeography(selection.object,1)
Y = objectgeography(selection.object,2)
End If
##############################
then select the object which has the coordinates within it (this is the best
i can come up with off the top of my head, there's probably a better way)
##############################
Select * from YourMap Where CreateCircle( X, Y, .001) Within YourMap.obj
##############################
i used ".001" as the diameter of the circle just so it's a tiny area and
should only be within a single region.
and this is all assuming your regions cover the entire area and do not
overlap, such as suburbs. if this is not true, then you'll have to make a
FindNearest function or something (not too hard).
see if this gives you some ideas.

Subject: MI-L run command error problem ... cont'd
Thanks again to all who responded to my run command error problem. Lars'
response was a great help in understanding why the problem occurs. Despite
all of the responses I am still unable to get beyond this problem in my
application.
If I explain what I'm trying to do perhaps someone might suggest a way to
achieve the results with out having to use an object variable in a query
expression:
* Using a tool button the user picks a point on the map
* If the chosen point is within a specific map object and a start
date matches a specified date then do something else
* If the chosen point is within a specific map object and a end date
matches a specified date then do something else
* If the chosen point is within a specific map object and a certain
fields match a specified criteria then do something else
* etc
Thanks again
