Hi,

I have a gdg file with some records in it, i want to create a header on it in such a way that all the related records(corresponding to one group, say for e.g one classroom) can be accessed easily later depending upon the header, Can you please let me know how a header can be created and accessed....

Thanks,
rahul.

Do you want to do this with COBOL or is it simple enough for a sort to handle?

With COBOL, you would create control breaks and re-write the file....
With a sort, there are 'HEADER' and 'TRAILER' functions....

Can you expand on your requirement?

Hi,

Please show some example of input records & the expected output for us to work on, BTW, if You need a JCL then rather appropriate forum is JCL instead of Mainframe COBOL, I guess.
