To compare two sequential or partitioned data sets you can use the MFJMATCH utility. MFJMATCH works in two modes, depending on the EXEC statement you use to invoke it:
| EXEC Statement | Description |
|---|---|
| PGM=IEBCOMPR | MFJMATCH emulates the IEBCOMPR mainframe utility. |
| PGM=MFJMATCH | MFJMATCH performs a data set comparison but does not emulate the IEBCOMPR mainframe utility. |
This section describes how to use MFJMATCH to emulate the IEBCOMPR mainframe utility. For information on using the non-IEBCOMPR version of MFJMATCH, see the section Comparing Data Sets (MFJMATCH).
