Moving from Vcursor to Vsets

Hi there,
I¹m trying to split up my SELECT statements into smaller chunks, using VSets
and the FindXxxx methods. I¹m wondering how would I select a primary key
such as this:
SELECT * FROM Tracks, PlaylistTracks WHERE PlaylistTracks.TrackUniqueIDPtr =
Tracks.UniqueID AND PlaylistTracks.PlaylistUniqueIDPtr = 3
(PlaylistTracks.TrackUniqueIDPtr is a Foreign Key Link to Tracks.UniqueID,
and PlaylistTracks.PlaylistUniqueIDPtr is a Foreign Key Link to
Playlists.UniqueID)
...using VSets? I can see how to do the individual selects using VSets, but
I can¹t see how to join the two together with the foreign key links.
I¹ve been doing it the VCursor way so far, but some of my SELECT statements
take too long to execute, so I want to chop them up into smaller chunks.
I¹m thinking of doing this using several VSet methods, each of which reduces
the set another step, bit by bit.
Thanks for any help,
Dave.
