1)
overlay : This is keyword which is used for overlays the storage of one subfield with another subfield in a data structure.

Ex:

D Datastructure DS
D Fullname 15a
D Firstname 6a OVERLAY(Fullname)
D Middlename 5a OVERLAY(Fullname:7)
D Lastname 4a OVERLAY(Fullname:12)

Even we can use OVERLAY(Fullname :*NEXT) instead of positions.
