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.
