Flash compiler encoded file that is generated when compiling ActionScript scripts (AS files) and stores bytecode for the script, that is compiled code readable and executable by the ActionScript Virtual Machine (AVM or AVM2). It is usually dynamically produced by the runtime compiler, so the user may not ever see the ABC file. They use a format called the "abcFile structure". This structure is made up of primitive information (integers and floating point numbers), structured information (executable code block with its constant information, type descriptors, code and metadata) and arrays (both primitive and structured information).
