Using IEBCOPY, you can re-create a partitioned data set from an unloaded copy of a partitioned data set by copying the sequential (unloaded) data set to a partitioned data set. A partitioned data set may be loaded from an unloaded PDSE if it does not contain program objects, and a PDSE may be loaded from an unloaded partitioned data set if it does not contain load modules.

You can create a single partitioned data set from multiple input sequential (unloaded) data sets.

For unload and load operations, requests are handled in the same way as for a copy operation. You can choose to process specific members and to rename them.

A partitioned data set in the unload format will have a variable spanned record format. When the unload data set is subsequently loaded, the output data set will have the same characteristics it had before the unload operation, unless you provide overriding characteristics when you reload the data set.
