Understanding the object names in Adobe Flash

Flash beginners might think that the object names in the flash library are the same as the instance names. However they most definitely are not. You should not confuse instance names, class names, or object names in your library. They all have completly different meanings in Adobe Flash. For example you can have red_box_01 is an instance name, redbox is the class name (without any spacing which is used to make instances with ActionScripts, red box is the object or movieclip with spacing in the library.
Moreover, red_box_01 is an instance of the red box movieclip in your library, you can have red_box_02, red_box_03, red_box_04, etc and they are all instances of the red box movieclip.
