@dick: As per your instructions, I downloaded cobol program. But I was not able to compile it. So I asked support people the cobol command to compile it, they said to download compilation jcl. I got one from google, but I have no idea what to do..
@skolusu: Thank you for providing the jcl. But the record length is aroung 7000 and there are numerous columns. And can we use copybook in jcl?
