Got to get to a meeting but the following may work.  I think there is a 
reserved word for record number.

SELECT MYFLD1, (ReservedWordHere) 
FROM ROB/MARKALLEN 
WHERE MYFLD1 IN 
 (SELECT MYFLD1 
  FROM ROB/MARKALLEN
  GROUP BY MYFLD1 
  HAVING COUNT(*)>1)

        Subject:        Best Way to find duplicate records in same file


I need to add duplicate record checking in a file we received from a
switch.  (I'll just add it to the CL that already FIXES a bunch of stuff
in the file anyways) and was wondering what the best (i.e easy/fast) to
do it would be.  I've come up with:
 
1.  Run a query against the file, sorted by entire record, level break
on entire record, count.  Output Query results to file and then do cpyf.
2.  Build a file keyed on all 210 bytes, read original chain to new
file, if not found write it
3.  SQL ???  not done much with it but maybe it could do?
