This installation exit allows you to modify the data set header (mapped by IATYNDH) of a SYSOUT data set (in a network stream) before JES3 or MVS/BDT transmits the network stream containing the data set.

This installation exit can be used to process BSC/NJE jobs and SNA/NJE jobs. The call indicator supplied as input to the exit indicates whether BSC networking or SNA networking is in effect.
