If I open a file in the OUPUT mode in the COBOL source program and in the JCL it has been specified as DISP=SHR, can I update/add records the file or will it result in a run-time error?
Can anyone send me a the guidelines or provide link to a forum which discusses the dispositions in a JCL and possible modes in COBOL program for file processing?
Thanks,
Vaibhav |

Morning Sir !
Why not just test it on your own. One little Cob-Programm and a JCL, just with a hand full of statements.
Afterwards you could be proud to tell us the result. |

| Don't forget to test with concurrent file updates. See if you get run-time error or bad data. |

Hello,
What kind of file is this? QSAM, VSAM, PDS. . .?
If you run a test that does not fail, be wary. This does not mean that this will always work correctly. |
