Visual Basic for Applications
     
         (VBA) {Microsoft}'s common language for
        manipulating components of its {Microsoft Office} suite.  It
        is used as the {macro} language for these applications and is
        the primary means of customising and extending them.  A VBA
        program operates on {objects} representing the application and
        the entities it manipulates, e.g. a {spreadsheet} or a range
        of cells in {Microsoft Excel}.
