IEBCOPY can be used for loading a Partitioned Dataset (PDS) from an unloaded file (backup of PDS). Unload files are created using IEBCOPY. Loading a PDS from an unloaded flat file involves recreating a PDS with members from the PS backup.

Practical Example -

Scenario - Re-create or Load a PDS from unloaded PS.

Explaining Example -

• SYSUT1 DD DSN=MATEPK.IEBCOPY.INPPDS,.. - Specifies the input unloaded PS file.
• SYSUT2 DD DSN=MATEPK.IEBCOPY.INPPDS1,.. - Specifies the new PDS that needs to create.
• SYSIN DD DUMMY - Load operation doesnt require control statements.
