I have a files containing both duplicate and non-duplicate records. The file is already sorted by a key. I want to determine those records that are duplicate and records that are non-duplicate. If duplicate the record is moved to a duplicate file and if non-duplicate that will be moved to valid file.

I am using COBOL, and occurence of records for duplicate and non-duplicate is more than twice.
