Write array variables outside AEA and import into actions.js

I have an array defined in document.compositionReady that defines captions for a series of images. Here is an example.

var myCaptionArray = new Array(''This is caption 1",  "this is caption2", "This is caption 3");

The captions are hard to edit in the Code Window because there is no word wrap. Is there a way to write these arrays in BBEdit or Dreamweaver and "import" them in to the actions.js file.
