please please please

i am not a good programmer .. but i like to learn

as previous flash releases i was getting around using external .as file

and now it seems to be an advantage to do such thing....

1- is there any beginner,step by step, class tutorial (please point me to it)
2- how to build a simple class?
3- how to use it inside my .fla?
4- can i import class from some related folder? refrence is .swf?
or from my website?


thanks in advance
