Bad Blocks Snap report
PCP generates the Bad Blocks Snap report (see the following figure) only under the Full Checking technique and only if requested with the SNAPBLK option.
The report is a dump of the IMS block that contains a detected error. PCP can print the block in OS/VS Dump format or DL/I format (the extended DL/I format is only available with the DL/I Block Dump utility). PCP prints the report to the PLUSSNAP data set.
