Removes an index from the current PSQL data file, and, if RefreshLocations is
True, also from the data dictionary definition for the current table.
The DdfDropIndex method syntax has these parts:
DdfDropIndex returns a two-byte integer that holds the status of the VAccess control. If this is zero, the operation completed successfully.
DdfDropIndex will drop the specified index from the actual data file itself. In addition, this function will remove the index from the metadata memory image of the VAccess control. If
RefreshLocations is
True,
DdfDropIndex will then update the DDF files themselves to match the current memory image. If
DdfTransactionMode is
True, these actions will be performed inside a transaction.
