The data to be sorted is created by Record Selection and Validation and placed in the data set referred to by the SMFOUT DD statement. The DCB attributes of this data set were copied from the input data set supplied to CRURRSV by the SMFIN DD. (See JCL for CRURRSV.) Therefore, the DCB attributes of the data sets to be sorted will match those of the SMF dump data sets that you originally supplied. Multiple data sets may be concatenated to the SORTIN DD statement for DFSORT if multiple runs have been made with CRURRSV.
