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.

2) CALL PGM(program name) PARM(A B C....) in CL

CALL 'Pgmname' Plist /*In RPG

Plist KLIST
PARM A
PARM B
PARM C

3)
RTVDTAARA in CL

RTVDTAARA DTAARA(DA1) RTNVAR(&Var)

We can use IN and OUT operations for reading and writing data area in RPG programs.
