To reference a library component from ActionScript file

Any help to solve this would be MOST APPRECIATED!.
I have a component in my library that I want to programmatically place on the stage and manipulate from my external actionscript file. I have a blank FLA and all the movieclips, text, etc that are on the stage have being created in an external ActionScript file and placed on the stage. However I would like to access this one component that is stored in my library without having to place it on the stage - since everything is to be done in ActionScript.
Is there a way to do this?
Kind regards and thanks for any help.
