Applescript LetterRip Server

I need to create an applescript which will export the subscriber list from a LetterRip Mailing List. The developer gave me the following code to get the addresses, but how do I save it to a file? I am not very good with applescript.

tell application “LetterRip_Server”
set a_list to subscriber list “test list”
set subs to subscribers of a_list
repeat with theSub in subs
set theName to name of theSub
set theAddress to email address of theSub
end repeat
end tell

Thanks for any help you can offer.
