You are correct, however I have found Unique indexes to be invaluable when developing. A lot of my work involves redesigning databases and migrating legacy tables into VFP. When I go to normalize a column, I create a temporary compact unique IDX to see the range of values I have to be concerned with ... I just couldn't do that with a Candidate key (even if I wanted to create a CDX)
