| IIRC, declaring cursors is not a program executable process, it is needed by the database preprocessor. Putting it in working storage reduces the procedure division clutter. |

| IIRC, nothing happens either way, it is non executable, (I think) it just needs to be visible to the precompiler prior to the cursor beiing used in the procedure division. |

Hai,
To my theoritical knowledge, I think the program will execute successfully but the problem will be with the performance of your program with respect to speed of execution. |

HUH? 
A lot of words with little said.....Where does the "performance" difference or problem occur in regards to where the cursor is declared?  |

| when the cursor is declared in the procedure division execution of your program will be slower than that of declaring it in the ws section |

Hi Yuvaraj ,
I don't think so & I m agree with William Declare cursor is non executable stmt it does not make any difference whether we declare it in working storage or procedure division it should be declare before open cursor stmt. |

Hello,
Replying to a topic that is nearly a year old is usually not recommended.
The answer given in the replies is that it makes no difference. |
