Résumé: VCL always creates DISTINCT style dBASE indexes
One side effect of this technique is dealing with deleted records. If you delete the record which displays when the unique index is chosen, no values for the record deleted will be displayed even though they exist in the database until the database is packed.
When Visual dBASE 7 was released it offered a new way to create unique indexes. It added the new option of creating unique indexes which are distinct. Such indexes operate in the manner that most other database operate in that duplicate values are prohibited.
Visual dBASE can create and use either style of index. Delphi and C++ Builder can use either style index, but can only create distinct unique indexes. So, if you need to create unique indexes which are not distinct you must use Visual dBASE to create them.
Visual dBASE is owned by dBASE2000. For additional information on Visual dBASE see www.dbase200.com
