What is the advantage of coding RECFM=F over RECFM=FB.I know the concept that RECFM=FB is fast, easily accessable due to the fact that FEW (not 1 records) records are allocated to each BLOCK. Then who would like to specify RECFM=F? And why?

Some old legacy packages/ programs had it. You may find it even now in old Cobol code as hard coded - you can't do anything without changing code and recompliling.

One of the reasons why F was needed - DA files (DA - Direct Access).

There are 2 or 3 types of them and the most popular one - REGIONAL1 had to have F format.

Nobody uses then anymore in application programming, but they are alive and well in some old tools/DBMS, like Datacom.

Thank you.
