Function
This exit gives control to installation exit routines during unallocation of sysout data sets. This exit is taken later in processing than exit 34. When this exit is taken, all the characteristics have been merged from the SSOB into the PDDB. Through this exit, an installation can control whether JES2 will spin the SYSOUT data set.
Unlike installation exit 34, which is taken once for an unallocation, installation Exit 48 is taken once for each PDDB associated with an unallocation.
