IEBCOMPR should never be used to compare

  1. Load Modules

  2. sequential data sets

  3. partitioned data sets

  4. PDSEs at the logical record level to verify a backup copy

A Correct answer
Explanation

IEBCOMPR compares datasets at the logical record level and should never be used to compare load modules because load modules contain binary machine code with address constants that may differ even when functionally equivalent. Sequential datasets, partitioned datasets (PDS), and PDSEs can all be compared using IEBCOMPR at the logical record level to verify backup copies.
