{Test 8: TIBDataset: Locate, Bookmark and Lookup}

{  This test uses IBX to access the employee database in console mode.
  The program opens the database, runs a query and writes the result to stdout.
  It includes SQL parsing, and parameter setting prior to opening. The dataset
  is also searched abd bookmarked

}
