Hello

This is a pretty basic question. Why do we need to separate Input and
Output Areas in display file? Is there any advantage in that? The reason
I am asking this question is because we do not do any such thing in RPG
programs. So why is it required in Cobol programs? Does it provide any
performance enhancements?

Many thanks in advance.

Regards,
Ravi Prasanna A.N.
