| What will happen if you code GO BACK instead of STOP RUN in a stand-alone COBOL program i.e. a program which is not calling any other program? |

Hello,
The program will end. Many system standards dictate only goback be used (rather than stop run).
GOBACK terminats the current executing code and returns control to the code that invoked it (this could be a calling program or the operating system).
STOP RUN terminates the run unit - sometimes rather ungracefuly. |

if you thinking GOBACK will call same program again then you are wrong.
is there any other reason that you are thinking so?[/code] |

Unless there is a flaw in the logical flow.. |

From the Language Reference:
| Quote: |
6.2.17 GOBACK statement
The GOBACK statement functions like the EXIT PROGRAM statement when it is coded as part of a called program (or the EXIT METHOD statement when it is coded as part of an invoked method) and like the STOP RUN statement when coded in a main program. |
If the program executes the GOBACK there is no infinite loop possible as the code is complete. If there is an infinite loop, the GOBACK is not being invoked. |

The Goback won't cause pgm to go infinite loop
Just understand purpose of STOPRUN and GOBACK first
STOP RUN - Will pass control to OS(operating system)
GOBACK - will pass control to Calling program
In above acenario, we are having GOBACK for Standalone program so when GOBACK executed, it will look out pgm which is calling since it is not calling it gives control back to OS..
So there is no question of Looping here, Pgm will execute succesfully
Hope you are clear |
