Short of running a FAVER "MAP" command in advance on each tape I would think you'd might be able to get the DRD folks to at least provide the functionality via it's LTAPE command to list the tapes contents. If they use your restore selector command can identify the object on the tape then they can identify object delimiters for listing of the contents. Of course, you could also write your own routine to list the tape contents.
