function aa (b:array of string) :boolean; begin showmessage('hello world ! '); result:=true; end; 請問如何調用這種function? 發表人 - donlly 於 2004/12/02 21:59:48

function aa (b:array of string) :boolean;
begin
  showmessage(b[ 0 ]);
  showmessage(b[ 1 ]);
  showmessage(b[ 2 ]);
  result:=true;
end;    procedure TForm1.Button1Click(Sender: TObject);
var
  a : array[0..2] of string;
begin
  a[ 0 ] := '111';
  a[ 1 ] := '222';
  a[ 2 ] := '333';
  aa(a);
end;

 unit Unit1;    interface    uses

  Dialogs, StdCtrls;    type      TArrayOfString = array of string;      TForm1 = class(TForm)
    Button1: TButton;

    procedure Button1Click(Sender: TObject);
