No it does not. You can have as many LFs as you want and as long as they
have the same keys, there will be only 1 access path.
In Frank's scenario, where you add a field to the PF and create a new LF
that includes the field for the programs that would need it. 99.9% of the
time, the new LF would have the same keys as existing LFs. So there is no
additional overhead.
