Jerry: I was under the impression that UV indexes are some kind of a linked list (e.g. each index key has all of the IDs associated with it in a single record). That's why BSCAN is needed to further process the list of IDs.
Whereas, UniData (and D3) actually uses BTrees where one traverses the tree with a single function. E.g. if I want "Smith, John H." I goto to "Smi]" and start traversing up and down with the same function as I want.

There is a t30 limit. Looks like default is 200. Do the indexes get counted among the 200? Or are they counted separately? Roger Ray Wurlod wrote: > The limit is 1000.
