Mark,

DDS keyword FIFO requires that you not reuse deleted records. Typically,
it is a very bad idea to create files without the attribute set to allow
the system to reuse deleted records.

Even in a case where you might determine that it is okay to not allow
the system to reuse deleted records today, tomorrow might be a different
story. In such a case, you would be facing a problem because the key
structure doesn't suffice.

And what happens to the arrival sequence path if you copy the file or
reorganize it over the key fields?
