With only 8 records in the cursor, I would select the matching records in a loop, a la
Select yourcursor
lnX=1
Scan
   lcVar = yourcursor.field1
   Sqlexec(lnHandle,'Select * from yourtable where yourfield = ?lcVar','curDummy' + transform(lnX))
   lnX = lnX + 1
Endscan
This will give you the necessary cursors which you can merge with a loop of Select * from .. Union all ..
