Sequential Data Sets

Table 1 shows basic and optional move and copy operations for sequential data sets.

Table 1. Moving and copying sequential data sets
Operation	Basic Actions	Optional Actions
Move Sequential	Move the data set. For DASD, scratch the source data. For non-cataloged data sets, update the appropriate catalog to refer to the moved data set.	Prevent automatic cataloging of the moved data set. Rename the moved data set.
Copy Sequential	Copy the data set. The source data set is not scratched. The catalog is not updated to refer to the copied data set.	Delete the catalog entry for the source data set. Catalog the copied data set on the receiving volume. Rename the copied data set.

When moving or copying sequential data sets on a direct access device, IEHMOVE execution time can be reduced by using multiple BSAM buffers for input and output.
