記録とmxをします.utils.StringUtil.substitute()パッケージを記録します.
 
    Using this class, the example above would look more like this:
    

receivedMessage=At %time%, you received a message from %userName%.
// then in your code
trace(ResourceStringUtil.getResoureceStringWithTokens("receivedMessage", {time: "11:49", userName: "Mims"}));
// displays
At 11:49, you received a message from Mims.
