DBRC authorization

Before any DBRC authorization, the Reorg function checks all data set names for logical errors.

Three sources of data set names are available: the data set names registered to DBRC, the input data set names in the JCL, and the output data set names in the JCL. Table 1 shows the possible combinations.
