Explanation

COBOL's internal SORT and MERGE operations are actually performed by DFSORT, IBM's high-performance sort/merge utility product. The COBOL compiler generates calls to DFSORT rather than implementing sort/merge logic itself. DFSORT is the underlying sort engine that handles all sorting operations for COBOL programs on IBM mainframes.
