This topic describes the data sets that are used to process SMP/E commands. These data sets are listed by the ddnames for the data sets required by each SMP/E command. According to the type of data set, you can define it with a DDDEF entry, a DD statement, or with GIMDDALC control statements in SMPPARM member GIMDDALC. For more information about DDDEF entries, see DDDEF entry (distribution, target, and global zone). For more information about SMPPARM member GIMDDALC, see Defining control statements in SMPPARM members. For more information about dynamic allocation, see SMP/E for z/OS User's Guide.
