When dealing with duplicate records in COBOL files, what are some common techniques for identifying duplicates?
- Comparing key fields
- Ignoring duplicates during file processing
- Using SORT and MERGE operations
- Utilizing COBOL intrinsic functions
One common technique for identifying duplicate records is comparing key fields. By comparing specific fields within the records, you can identify duplicates based on the values in those fields. This is often done using logic within the COBOL program.
