GOBACK statement
The GOBACK statement functions like the EXIT PROGRAM statement when it is coded as part of a called program and like the STOP RUN statement when coded in a main program.
The GOBACK statement specifies the logical end of a called program or invoked method.
EXIT PROGRAM statement
The EXIT PROGRAM statement specifies the end of a called program and returns control to the calling program.
You can specify EXIT PROGRAM only in the procedure division of a program. EXIT PROGRAM must not be used in a declarative procedure in which the GLOBAL phrase is specified.
STOP statement
The STOP statement halts execution of the object program either permanently or temporarily.
When STOP RUN is specified, execution is terminated and control is returned to the system. When STOP RUN is not the last or only statement in a sequence of imperative statements within a sentence, the statements following STOP RUN are not executed.
The STOP RUN statement closes all files defined in any of the programs in the run unit.
