record with duplicate key

["Ray, Adam" <aray@xxxxxxx>]

I'm having a problem with a program which adds records to a file. I get
error code 01021 - Tried to write a record that already exists.
I looked at the program dump and determined what the key of the record it
was trying to write was. Then I looked in the file it was writing to and
found one record that was SIMILAR to the record being written, EXCEPT for
one field in the key was different. The key I am using is comprised of 10
fields, the 4th one being a signed packed decimal in descending sequence.
All other fields are character. The field that is different in the 2 records
is the 5th field of the key. Why is it saying I'm trying to write a
duplicate key when the keys are different? Is it something to do with the
DESCEND keyword on the signed packed decimal field? What is going on here,
I'm stumped?
