Entry-sequenced data sets are accessed by address, either sequentially or directly. When addressed sequential processing is used to process records in ascending relative byte address (RBA) sequence, VSAM automatically retrieves records in stored sequence.

To access a record directly from an entry-sequenced data set, you must supply the RBA for the record as a search argument. For information about obtaining the RBA, see Entry-Sequenced Data Sets.

Skip-sequential processing is not supported for entry-sequenced data sets.
