Answer / neha
we use export for backing up data from vsam dataset to a ps
and import is used for transferring data from ps to a vsam
dataset.though repro can do the same but the difference
lies in the fact tht export also extracts the catalog info
of the vsam so tht the vsam dataset can be easily rebuld
later on...
