I need to write a cobol program to read and treat all JCL that are in a PO file. I wrote the program to do it, but it is abending with I/O error.
Can same one help me how to specify the SELECT clause for this kind of file?

Hello Rildo and welcome to the forums,

If you post 2 or 3 sample members that will be "input" to your program and the output you want when those members are processed someone may have a suggestion.

If will also help if you post your jcl and the error message you are currently dealing with.

Would you by any chance be trying to read and rewrite the same member? What error are you getting?

As another thought, I would think that for working with PDS's, the use of ISPF Library Management (LM) services might be beneficial.

Hi,

I'm no COBOL programmer but I'm not sure you can specify organisation of PO in your SELECT statement, so I believe you need to specify each member on a separate DD statement in your JCL.
