For each definition entry in the originating zone, SMP/E checks to see whether that entry exists in the destination zone.

• If the same-named definition entry is not found, the entry from the originating global zone is stored in the destination global zone.
• If the same-named definition entry is found, then processing continues based on the type of definition entry.
• For DDDEF, FMIDSET, OPTIONS, ORDER, UTILITY, and ZONESET entries, if the originating global zone contains an entry that does not appear in the destination global zone, then the entry from the originating global zone is stored in the destination global zone. (The DDDEF entries for the SMPPTS and its spill data sets are not merged by GZONEMERGE processing.)
• For the GLOBALZONE entry, processing continues to determine which subentries within the GLOBALZONE entry to merge.
