The program wont go into aninfinite loop!!!
The results are same while using GOBACK or STOP RUN.
Except in the first case if there is a calling program control will pass back.
 The programmer can use any of these 2 commands to end pocessing....

If GOBACK is coded instead of STOPRUN in a cobol program which is not called by any other program, nothing wrong will happen. The program will give desired results.


Generally 3 things are coded to halt the execution of a program, they are

STOP RUN
GOBACK
EXIT PROGRAM

STOP RUN is frequently used and mainly coded in main programs(calling program). The control will be returned to OS.

GOBACK is coded in the mainly in the subroutines or called programs. The control will be returned to the calling program. If STOP RUN is coded in the calling program, the program will go to an infinite execution. GOBACK can be coded in the programs which is not called by any programs instead of STOP RUN.

EXIT PROGRAM is seldom used.

In case of subprogram, GOBACK or STOPRUN used to terminate the sub program, but when it is used in main progarm it will cause the program to terminate.

Stoprun gives back control to OS . Goback will give back control from where the control was achieved.

If goback is coded in sub program the control will be passed to main program, if Goback is coded in main program itself then control will be passed to OS.

So if goback is coded in a cobol program instead of Stoprun there will be no problem,But if stop run is coded in sub program the program wiil abend.

When the goback is specified in the mainprogram, the control will go back to the runjcl from which step the control came. It will start executing the next step in the JCL if available, the program will continue normally.
