OK... here's a go at it:

LOCAL ARRAY laFields
LOCAL lcOn, lnI

lcOn = ""
SELECT <either table>
FOR lnI = 1 TO AFIELDS(laFields)
  lcOn = lcOn + IIF(EMPTY(lcOn),"ON "," AND ")
  lcOn = lcOn + "FreeTable." + laFields[lnI,1] + " = DBCTable." + laFields[lnI,1]
ENDFOR

SELECT FreeTable.* ;
  FROM FreeTable ;
  LEFT JOIN DBCTable &lcOn ;
  WHERE FreeTable.Field1 # DBCTable.Field1

The resulting cursor will contain only the records from the FreeTable that couldn't be matched with a record in the DBCTable. Replace Field1 in the WHERE clause with any field name - in the join, the unique records will have all fields in DBCTable = .NULL.

You should be aware that in order to Rushmore optimize the query, you'd need an index on every field in both tables.
