        We use a product called delphi/400.  This uses record level access
and
        performs down in the .1 sec range  /record on our 170.


        *** Can you give me the vendor details please ?


        Have you tried creating a logical file which would select only the
        records which are in error?  It sounds like the package you are
using IS
        sending the whole file to the PC.  I have run into this problem with
        various packages - the actual record selection is done at the PC
level
        (ODBC has done this to me).  If you cannot create a logical maybe
you
        can have the Delphi app run an as400 program that extracts the
records
        and then open that file ?


        *** Yes we have tried using  logical files. Yes there is a
difference, but it is still too slow. After creating the logical files it
still takes 30 to 35 minutes.  The package we use does not download the
whole database to the PC. It accesses the 
        AS400 database by creating a  DDM file.  

        I agree  with you that, ODBC can be really nasty at (perhaps always)
times.  I will try to get the  Delphi app. run an AS400 program. 

        The largest file we are working with in Delphi 400 is only about
200,000
        records but we expect sub-second response time unless the system is
        heavily loaded.

        * Our file size is also in the same range.



        Thanks  a million John.


        Cheers
