Thanks so much for the suggestions. I have modified your code to look like this:
Select * from MyTable
where taxid = 'SUTATX'
set order to prempl
lprempl = Null
scan
IF lprempl = MyTable.prempl
Delete
ELSE
lprempl = MyTable.prempl
ENDIF
ENDSCAN

The table has two indexes, prempl and taxid. I want to delete the second taxid=SUTATX for each prempl. I am just learning FoxPro, so forgive my ignorance. When I run this code, I get some error and I don't know how to figure out what the error is.
Am I way off with this code?
