Another way of accessing a key-sequenced data set is addressed access, using the RBA of a logical record as a search argument. If you use addressed access to process key-sequenced data, you should be aware that RBAs might change when a control interval split occurs or when records are added, deleted, or changed in size. With compressed data sets, the RBAs for compressed records are not predictable. Therefore, access by address is not suggested for normal use.
