I have some old COBOL programs and I need to convert them to Enterprise COBOL.

I have this Select statement.

What does the above NOMINAL key word mean ?

Can I just remove the NOMINAL keyword it as it says in the below link ?

I also get the below error




The file concerned is temporary so I couldnt do a listcat.I will try to create it as a non temporary file and look at its properties tomorrow.

The read statement is made as if it were a Random access file.




Can someone please explain me why I get the below error ?

Below is the complete message..

Below is how the file is created.


I apologize for taking multiple posts to post the relevant information.

This is for a "DA" data set. I don't know when those ceased to be supported in IBM COBOL, but a while ago.

You will replace it with a VSAM KSDS, and make a SELECT appropriate for that.

I think this COBOL program may have originated on DOS/VS, the SYSnnn is more at home there, but maybe just an inherited style.

Thanks Billyboyo.

I tried looking up for DA datasets but didn't find enough documentation.Is it same as a BDAM dataset ?

Yes, BDAM is the access method for a COBOL DA data set. It could be replaced by a VSAM RRDS or KSDS, depending upon the application.

Hello,

In general if one ever gets stuck in trying to figure out how/what a data set type is, the best place to start the search is DFSMS Using Data Sets; Look at the chapter: 'Processing Direct Data Sets'.

Hope this helps.
