Example:
Input File1:
000 1111 12356908
001 1212 54321234
002 1323 78654323
003 5656 98765456
Input File2:
000 1000 12356908
001 1212 99999999
002 1323 77777777
003 5656 88888888
Output File:
When EQUAL(1)
000 1000 12356908
000 1111 12356908
When EQUAL(2)
001 1212 54321234
001 1212 99999999
002 1323 78654323

Answer / brian
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.
