Call me old school, but all my master files have a key defined in the DDS.
They also get reorganized monthly.

IMO, anything that is a master file should not only have a key on the
physical file, but it should be a unique key.

Also, all logical files over the master file should include those key
field(s) so that the physical order of the records never impacts the
ordering of the logical files.
