SMP/E V3R1 allows you to define exit routines that are to be given control during SMP/E processing by specifying new GIMEXITS control statements in SMPPARM member GIMEXITS. This replaces the previous method of updating module GIMMPUXD. Putting the exit routine information in an SMPPARM member means that the information is persistent and that you do not need to update module GIMMPUXD every time a new release of SMP/E is installed.
