How to check negative integer values ? – PROGRESS 4GL

I have written a below query to see what are the possitive and negative integer values from a table fields. But I am not sure how to fetch only negative integer values.

DEFINE TEMP-TABLE ttdata NO-UNDO
FIELD iValue1 AS INTEGER
FIELD iValue2 AS INTEGER
.

CREATE ttdata.
ASSIGN
iValue1 = 122
iValue2 = -122
.

FOR EACH ttdata NO-LOCK:
  DISP iValue1 iValue2.
END.

>Solution :

a query just about one field where field < 0

FOR EACH ttdata NO-LOCK 
   WHERE ttData.iValue2 < 0:
    DISP iValue1 iValue2.
END.

when you have two fields with or, but dont use it on a real database table because it is very slow without any index

FOR EACH ttdata NO-LOCK 
   WHERE ttData.iValue2 < 0 
      OR ttData.iValue1 < 0:
    DISP iValue1 iValue2.
END.
