1.先在畫面拉一個輸入文字，取名為 input_txt
2.隨便做一個按鈕，取名為 save_btn
3.在主時間軸貼上程式碼：

AS2.0
var so:SharedObject=SharedObject.getLocal("mySaveData", "/");
if(so.data.mySaveData!=null){
input_txt.text=so.data.mySaveData;
}

save_btn.onPress=function(){
so.data.mySaveData = input_txt.text;
so.flush();
}

AS3.0
var so:SharedObject=SharedObject.getLocal("mySaveData","/");
if(so.data.mySaveData!=null){
input_txt.text= so.data.mySaveData;
}

save_btn.addEventListener(MouseEvent.CLICK, function(e:MouseEvent){
so.data.mySaveData = input_txt.text;
so.flush();
});

//---------------------------------------------------------------------------------------------------------
檔案位置：
var so:SharedObject=SharedObject.getLocal("mySaveData", "/");
檔案在：
C:\Documents and Settings\登入者名稱\Application Data\Macromedia\Flash Player\#SharedObjects\xxxxxx\localhost
檔名：mySaveData

如果是寫var so:SharedObject=SharedObject.getLocal("fun/mySaveData", "/");
檔案會在：
C:\Documents and Settings\登入者名稱\Application Data\Macromedia\Flash Player\#SharedObjects\xxxxxx\localhost\#fun
檔名：mySaveData
