==========================================================
TTouchJunction = class(TCustomApplication)
  protected
    procedure DoRun; override;
    function DateTimeToFileTime(DateTime: TDateTime): TFileTime;
  public
    constructor Create(TheOwner: TComponent); override;
    destructor Destroy; override;
    procedure WriteHelp; virtual;
  end;
==========================================================

I'm an old Turbo Pascal (mainly 3.x, a little 5.5) guy and don't
remember or never saw override and virtual. What do they do?
