O/P file defined in the SELECT STATEMENT of the COBOL program but not defined in the JCL - respective DD statement is not mentioned in the file but still in the program the WRITE operation is performed successfully. How this is possible Confused

?

Vinodch,

Your Write was successful because of the Language environment parameter CBLQDA . CBLQDA(ON) is the setting that dynamically allocates with DISP=(NEW,DELETE,DELETE) file when an output DD name is opened but missing from the TIOT.

Check this link for a detailed explanation.

Vinod,
When you are saying that the WRITE is successful, do you mean that, the record is written AND the output file is also created ?

If the file is created, then I would guess that there is a program specific to your site that is doing dynamic allocation. The LE dynamic allocation will not come in affect here as the DISP=(NEW,DELETE,DELETE) (as mentioned by Kolusu).

Yes our LE environment has CBLQDA(ON) that' Very Happy

s the reason the write was successful. I tried the job with CBLQDA(OFF) the job abended.

Thanks Kolusu & Cogito-Ergo-Sum.

I could also able to list down the various default option for the LE - Are there any links that explains what for the each option stands for ?

Any Help Appreciated !.
