'reading' but not 'including' an .as file?

is there an efficient way to ‘read’ an external .as file? using ‘#include’, it get’s integrated on publish, but could it be ‘loaded’ instead, so that a change to the external text file would update a previously published .exe/.swf?

…this is another interpretation of my earlier post!
