Reply with quote

Hi,

I am in a Unisys Migration project. In unisys, they can directly check from the program whether a file is present or not.

If present <do something> else <do other thing.(business functionality invloves here)>.

But in IBM side if the file is not present it will throw jcl error, it will not enter into the program.

But I want even if the file is not present it will enter in the program execution. Is there any way to do it?

Note: I know the file existence can be checked by IDCAMS, LISTCAT thru the jcl. But I need that checking should be done from program.

Let me know if any more information is required

Regards,
Ashim

The QSAM file is implicitly created if you use the runtime option CBLQDA and one of the following circumstances exists:An optional file is being opened as EXTEND or I-O. Optional files are files that are not necessarily present each time the program is run. You define a file that is being opened in INPUT, I-O, or EXTEND mode as optional by coding the SELECT OPTIONAL clause in the FILE-CONTROL paragraph. The file is being opened for OUTPUT, regardless of the OPTIONAL phrase


probably would help you if you read the ibm manual concerning COBOL
