Table 1. DFSMSdss Installation Exit
Name	Usage
ADRREBLK	Data Set Reblock Exit: System-managed and non-system-managed data sets. Called if REBLOCK is specified for COPY or RESTORE. If the VTOC entry for the data set indicates that the data set is reblockable, the data set is always reblocked and the ADDREBLK exit is not taken. Return from the exit with a return code of 12 to enable the data set to be marked as reblockable. Be aware, however, that some data sets (such as load libraries) are sensitive to reblocking.
