The Save Data Base Dependent LFs and Restore Data Base Dependent LFs commands
provide a solution for the case where a logical file is built over a physical
file in another library and a system restore is needed. SAVDBDLF must be run
prior to the save of the system. RSTDBDLF is run after the restore of the
system to restore the logical files. Access paths may be rebuilt. A few LFs are
created, saved by SAVDBDLF, then deleted before RSTDBDLF is run.
