There's no limit.

if you are giving sysin dd * for a cobol program then maximum limit is 64kb since max size of working storage canbe 64k only.

Well, this question was posted in the JCL forum, not a COBOL forum, so I'm not sure how you both are making any conclusions about this being specifically related to COBOL.

I have seen many Remote Job Entry (RJE) jobs where literally Gigabytes of data are passed instream to an output dataset, so I stand behind my original answer.

Now, if the O/P wishes to elaborate further, or clarify the question, then maybe the answer might be different. Although, even though I'm not a programmer, I could swear that I've read that the W-S section can contain many Megabytes of data.

You're right Kevin. I don't know where they get their info. It's a bit bizarre.

Try this link guys:
