***********************************************************************
* *
* SEQXMP2 - THIS MODULE WILL READ THROUGH THE DSCBS ON A *
* NONINDEXED VOLUME. IT WILL USE THE CVAFSEQ MACRO *
* TO READ UP TO 5 DSCBS AT A TIME IN PHYSICAL *
* SEQUENTIAL ORDER. *
* OUTPUT FROM THIS MODULE WILL BE TO OUTDD. IT WILL *
* LIST ALL OF THE DATASETS ON THE VOLUME AND THEIR *
* CORRESPONDING CCHHR'S. THE FMT4, FMT5, AND FMT7 DSCBS *
* AND THEIR CORRESPONDING CCHHRS WILL NOT BE LISTED. *
* *
* THE FOLLOWING DATASETS WERE ALLOCATED IN THE FOLLOWING *
* ORDER ON A NONINDEXED VOLUME. *
* 10 SEQUENTIAL DATASETS: CVAFSEQ1.SEQ01-CVAFSEQ1.SEQ10 *
* 5 PDS DATASETS: CVAFSEQ1.PDS01-CVAFSEQ1.PDS05 *
* 5 PDSE DATASETS: CVAFSEQ1.PDSE01-CVAFSEQ1.PDSE05 *
* 2 VSAM DATASETS: CVAFSEQ1.VSAM01-CVAFSEQ1.VSAM02 *
* *
* NOTE: THE OUTPUT FROM THIS EXAMPLE IS BASED ON USING A NON SMS *
* MANAGED NON INDEXED VOLUME FOR ALLOCATING THE TEST *
* DATASETS (CVAFDD DD). *
* IF A SMS MANAGED NON INDEXED VOLUME IS USED THE POSITION *
* OF THE VVDS DATASET WILL BE THE SECOND ENTRY IN THE LIST. *
* *
* DASD VOLUMES USED IN THIS EXAMPLE: *
* - 1 3390-3 WHERE THE OUTDD DATASET IS DEFINED *
* - 1 3390-3 WHERE THE TEST DATASETS DETAILED ABOVE ARE DEFINED *
* THIS VOLUME INITIALIZED USING: VTOC(3326,0,195) NOINDEX *
* *
* *
* *
* OUTPUT IN OUTDD DATASET SHOULD BE THE FOLLOWING: *
