What do you teach? I might be able to learn something here. Also, does AS have some kind of onError or anything like that?

try

catch

throw

finally

function setDimention(num:Number){
    try{
        //here's what happens whne we assign a meanless number
        if(num<0){
            //the throw operator throw an temp instance of the Error class
            throw new Error("the number is smaller than 0")
        }
        //now, if that's the case, all statements in the try block stop, and Flash execute the catch block
    }catch(e:Error){
            //e is the instance of the Error class, the message property is the message. You can have more than one catch block
            trace("an error occurred :"+e.message)
    }finally{
            //this code will always execute, even if there's an Error(which cause the try block to end)
            trace("hello")
    }
