The top section of the Data Set Information – VSAM LDS screen contains the DSN of the cluster and data components of the Linear Data Set VSAM file. To the right of the DSN of the data component is the volume serial of the first volume. If the component has multiple volumes defined, the volume serial will be followed by a plus sign (+).
