Coding STOP RUN or GOBACK would not depend on whether it is an IMS program or not.
It depends where it is being coded, whether in a MAIN Program or SUB PROGRAM.
Check out this from manuals....
| Quote: |
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. |

Priyesh. |

hi Priyesh,
it does depend on coding STOP RUN or GOBACK for IMS program. For IMS COBOL program we must code GOBACK instead of STOP RUN. only then all your resources acquired from IMS by the ENTRY statement will be released back to IMS.
suggestions welcomed.

| U are correct Gowtham and ims cobol program acts as a sub program to IMS and hence we should use GOBACK to return the control to Main program (Which is IMS system) |

ya , we write STOP RUN. at the end of the cobol prog.
Its manditary that every program ends with stop run, inspite of number of para s that we have used.If dont use STOP RUN the program compiler that is IGYCRCTL will through the error.

Hi Venkat,
i belive we use different compilers for normal COBOL program and IMS-COBOL program. So IMS-COBOL program should always be terminated with GO BACK and a normal COBOL prg shoud be terminated with STOP RUN.
Please correct me if i am wrong... |

IMS cobol pgm should be coded with GOBACK as above said it results in logical ending , also it results in proper closing of log files and VSAM files and deallocation of OS resources.
If STOP RUN it result in forced termaination of pgm, which i believe results in ABEND |

With the use ENTRY statements, what do you mean acquiring resources?
Does it mean that those DBs will not be accessed by any other programs?

IMS COBOL or IMS PL1 program are always Sub program to DLI Main program, and ENTRY statement gets control from DLI.
All the PCBs are loaded, DB pointers are setup, etc

It doesnt mean that those DBs will be locked.
Mahendran B - When starting a new discussion, better to post new topic rather than chaining in some other topic. |

I love it when IBM publishes information on the net 
this one and this one for example. There's a sticky in the forum leading you to IMS information  |

Hello,
FWIW (For what it's worth), many sites i've worked with/supported will not allow STOP RUN in any production code. |

| Check the version of IMS on which you are working. If the version is greater than 7, then both stop run and goback are valid and both do the same functionality if it is ur main program. if it is ur subprogram, use goback or exit program command. |

hello,
IMS programs run under the control of batch initilization module DFSRRC00.If you code Stop Run the control is return to OS instead of DFSRRC00. So code GOBACK to give the control back to the called module its DFSRRC00. |

This item was posted and, however we answered it, TS did not react at all. IMHO we should not pay any attention to it anymore. |

Hi,
My understanding is that irrespective of IMS COBOL or a normal COBOL program, using GO BACK is good and this will give a chance to OS to release all the resources allocated to the program. |

| The answer is simple - ALWAYS-ALWAYS-ALWAYS use GOBACK. Does any version of COBOL support STOP RUN anymore - if it does, it shouldn't. GOBACK allows you to enjoy the privilege of becoming someone's called program. |

Hello,
While the compiler still supports STOP RUN, many organizations do not allow it to be used. One of the things checked in the promotion process is that GOBACK is used and there is no STOP RUN in the code.
As many others have said - use GOBACK. |

| Yeah, I'm with Dick on this one. We don't allow STOP RUN anywhere in our code, we use GOBACK for everything. |
