The mds file in D3 is equivalent to the system file of R83 and Pick compatible systems. To restore Q-pointers to D3, a sel-restore can be performed, but a different method should be used than for a restore of mds from a D3 tape. The specific command or options used may vary depending on the source system. We recommend restoring items to a non-mds file, checking that file, then copying the desired items to mds. This keeps unwanted items out of mds.
