Hi All,

I have a JCL in which I want to skip the processing if the VSAM file is not present. If the file is present, then I want to go execute all steps in the JCL.

Can this be achieved using IDCAMS ?

Best regards,
Amit.

Hi Expat,

This is what I could think of using IDCAMS -

Define a file using IDCAMS, if return code is 0 - Skip processing, if return code > 0, then continue processing

Is there a better approach ?

Best regards,
Amit.

I'd go the other way around - LISTCAT to see if the file exists and execute accordingly.

If you set the file up, then the next time that you run the job, the file will exist so will cause the process to execute. Checking to see if the file already exists is safer.
