Merging Data Sets
Merging Data Sets
Summary
For basic information, go through the IEBCOPY Utility (for Beginners)
- IEBCOPY can perform the merge operation to merge the datasets.
- Data sets merge by copying or loading the additional members to an existing PDS.
- Ordering of the output data set after merge can be done automatically.
Practical Example -
Scenario - Re-create or Load a PDS from unloaded PS.

Explaining Example -
- INPPDS1 DD DSN=MATEPK.IEBCOPY.INPPDS,..
INPPDS2 DD DSN=MATEPK.IEBCOPY.INPPDS1,.. - Specifies the input PDS file. - OUTPDS DD DSN=MATEPK.IEBCOPY.OUTPDS - Specifies the output PDS.
- COPY OUTDD=OUTPDS
INDD=INPPDS1
INDD=INPPDS2 - Specified INPPDS1, INPPDS2 are inputs and OUTPDS is output.
