Sort the file in ascending order of your duplicated fields.
You can write a COBOL module to read the file sequentially.
Set up a dup-counter in Working Storage. Set up a group of
fields in Working Storage to hold duplicated fields. They
should be similar to what you are sorting on. Save each
records read fields after reading it. When you read the
current record compare it to the saved fields. If they
match add to your dup-counter. If they don't match zero
out your counter. After adding to your counter check the
value. If > 1 you have a 3rd duplicate. Write that record
to a duplicate output file. Hope I'm close to getting you
an answer.
