hi,

In the below code, the VSAM file is initially opened in the output mode and then it is closed in the next line itself. after that it is again opened in the i-o mode. Please let me know why the vsam file is opened like this?

Hello,

The initial open/close is to prevent a possible error when the file is opened i-o.

If you click on the "Manuals" link at the top of the page, you will see a list of links to the current IBM product manuals. There is a VSAM services manual and several COBOL manuals. Coding info is in the COBOL manuals.

dick,

Could you tell me what you are referring as a possible error?

Thanks for the manual information.

Thanks,
Bala

You're welcome

When a "new" vsam file is opened without being "initialized" an error is raised (don't recall exactly which one just now, but i believe it is mentioned in some other topics). Opening/closing the file as output prevents the i-o open from being confused.
