Formatting textfile for Combobox.dataProvider

Question

Can't seem to find any formatting rules for array
construction through an external file.
This is what i am trying to do:
I've loaded vars into the _root this works fine. Splitted its
value for constructing an array. This seems to work fine aswell.
If I code the array within the fla in this format:
my_dP= new Array(
{label:"choose..."},
{data:"
http://www.myserver.com/netlabel/Johannes
Lauxen.txt",label:"Johanes Lauxen"},
{data:"
http://www.myserver.com/netlabel/PQR1.txt",
label:"PQR1"}
and use this for the dataProvider for the combobox named
my_cb like this:
my_cb.dataProvider = my_dP;
everything works fine.
The problem is:
But if I put this in the same formatting in the textfile for
the array I create using split like I described above, the values
for my labels in my_cb are this text, i mean it doesn't
interpretate the loaded text as script, it just displays the code
as labels.
my textfile looks like this :
&var2={label:"choose..."}#{data:"
http://www.myserver.com/netla
bel/Johannes Lauxen.txt",label:"Johanes
Lauxen"}#{data:"
http://www.myserver.com/netlabel/PQR1.txt",
label:"PQR1"}&
(O, the # is used for delimiter)
How can i get this to work ? Or is it not the
textfileformatting that causes the problem ?
many thanks
