Andy,
I am very concerned about how the corruption had occurred also.  But it
seems that the majority of the corruption and probably all of it occured
during a conversion since the data goes up to 1999.  This was a S36 package
and still uses mostly S36 Cobol.  Recently though we have been implementing
the reporting process in Sequel which is SQL based and when we encounter one
of these situations it generates huge joblogs.

I was able to fix the particular field that I had problems with using SQL
for an update.

statement follows:
UPDATE NCTPFT16/"T16.COAD" SET ODAAMT = 0 WHERE hex(odaamt) =
'0000000000'

As I indicated prior the field contains all hex 0's and should have the F as
the low position.  So as I staed I have been able to find a solution to my
problem.

Thanks again.

Ron

Ron,

Perhaps the easiest method would be to write a simple program which
would examine the hex data within the field (redefine the field to
character data) and then update the last byte to x'0F'.

I assume that you are referring only to the last byte of a packed field.
Having a value of x'00' in the middle of a packed field is normal.

Can you give an example of the hex value of a bad field?  What is it?
What should it be?

I would be concerned about how such corruption could occur.

Regards,
Andy Nolen-Parkhouse
