VSAM Define panel

You can use the VSAM Define panel to specify the allocation attributes for a VSAM data set. This panel has five variations, one for each VSAM data type supported by File Manager (KSDS, ESDS, RRDS, VRRDS, LDS). For general information about defining data sets, see the DFSMS Using Data Sets manual appropriate for your operating system. For specific information about valid field values, use the field-level Help (put your cursor in the field and press F1).
