ActionScript
From Just Solve the File Format Problem
ActionScript is a variant of JavaScript / ECMAScript designed for creating applications for the Adobe Flash player (embedded in SWF files). It is an object oriented language designed for attaching actions to elements within the Flash animation for the purpose of interactivity, but has been enhanced in successive versions to become a full-featured programming language.
ActionScript Byte Code is a byte code version of ActionScript run by the ActionScript virtual machine, generated by a compiler.
