SMP/E V3R1 allows you to define data sets to be dynamically allocated by SMP/E by specifying new GIMDDALC control statements in SMPPARM member GIMDDALC, as well as by using DDDEF entries. This replaces the previous method of updating module GIMMPDFT. Putting the dynamic allocation information in an SMPPARM member means that the information is persistent and that you do not need to update module GIMMPDFT every time a new release of SMP/E is installed.
