A program is disclosed which makes defining catalogs and datasets under the virtual storage access method (VSAM) an easy and quick job. The tasks that are performed by this program are: verifying the format of the specified disk, determining the type and size of the disk, generating a VSAM unique catalog name, calculating the catalog and dataspace sizes, defining the catalog, and defining and initializing VSAM datasets. Successful processing with this program reduces these tasks from more than hour of work to only a few minutes for a disk. This program is used after the preliminary formatting of the disk is completed using the DOS disk formatting facility which makes the disk ready for VSAM catalog and dataset definitions.
