Explanation

IEBCOPY is the IBM mainframe utility used for copying and compressing Partitioned Datasets (PDS). It can copy entire PDS libraries, merge members, and compress unused space within PDS files to reclaim storage. IEBGENER copies sequential datasets, IEFBR14 is a dummy program, and IDCAMS manages VSAM and GDG datasets.
