AS3 internal code to external

I’ve used kirupa.com as a resource for several years. You all have been so much help.

I’ve got a project that I’ve been avoiding because it’s something I’ve never done before. I have a concept game that I put together with internal AS3. I wasn’t given much time make it work, otherwise I would have done the code externally to start.

The project is now ‘go’, but I want to convert the crappy internal code to external. I don’t have any of those fancy IDE’s. I could get one, if it would help.

Does anyone know of any tutorials covering internal to external conversion? Has anyone else done this? Is there a simple list of things to convert to make the code work externally?
