As
La palabra reservada As pertenece a la programación orientada a objetos y se utiliza para convertir (TypeCast) un objeto en una clase. Para ello, el objeto debe ser una instancia de la clase.
Ejemplo:
procedure TmainForm.selectionGridDrawColumnCell(Sender: TObject; const Rect: TRect; DataCol: Integer; Column: TColumn; State: TGridDrawState);
begin
(Sender As TDBGrid).DefaultDrawColumnCell(Rect,DataCol,Column,State);
end;
Aquí la variable Sender del tipo (type of) TObject se convierte/asigna como (as) tipo (type) TDBGrid.
