Can dBase have a PK? I need to have just one column set as a PK to ensure that duplicate data does not happen. I am using dBase4.
 
I would say
SET UNIQUE ON
then create an index and always handle your database with that index open

I'm not sure what dBase does if you try to add a record with the same key. You can try.

Using SET UNIQUE ON will always give you the first unique occurance of a record. Using the COPY TO command will create a table with only those unique records.
