What Nadya said about LOOKUP(), but one of your problems here may be that SET EXCLUSIVE is scoped to the DataSession (see the help under SET DATASESSION for a full list of commands.

(Do you want to call the variable loNewDS, btw?)

Also, you might want to write your search as follows -- mileage may vary, of course.

SELECT 0
USE people SHARED
IF SEEK(tcEmpNo, "people", "empNo")
*!* etc.
