I think you need to think 'misc' 'dosc' with your own data structure and
content. 

Google the following "dosc misc revolution" and look at a couple of the
archive posts on  our list.

on appleEvent theClass,theID
   if theClass is "misc" and theID is "dosc" then
      request appleEvent data
     put it into thedata

Ken Ray has some good help pages on the use of appleEvents
