External text as ListBox DataProvider

Hi All,
I have a MX 2004 ListBox. I need to populate it from an external text file (so the client can update the list without cracking open the .fla).

I know the v2 ListBox DataProvider is an array - how do I get the dataprovider to access the array from an external text file.

Could someone please show me the syntax? I assume it involves using loadVariableNum, then assigning that to the data provider. MX 2004 Help waffles on about creating the dp arrays inside the .fla using the dp API.
I have searched the web, the MX help files and the “Using Components” Book.

Thanks in advance.
