There's a carbony technical Q&A document which has source code : QA 1111
http://developer.apple.com/qa/qa2001/qa1111.html
The idea is that
1) a compiled script is included with the application. This script has (at least) a handler with a name like 'patricks_handler' which takes a list of arguments
2) At runtime, that script is loaded with OSALoad, which results in an OSAID context.
3) You create an AppleEvent of class: 'ascr' id: kASSubroutineEvent -- you supply the subroutine name and your list of parameters there.
4) Instead of sending the event with AESend, you call OSAExecuteEvent with the event and the context.
The advantage over compiling your script on the fly is that the script only needs to be compiled once, at compile time if you'd like, and there's no need for the GetAETE event.
And although it's too late now, this is probably a better discussion for the applescript-implementors list....

Hmm, could you elaborate on that last sentence? It sounds very
interesting, but I don't fully understand it ;-)
As far as I know, I could implement this strategy by setting up an
NSTask to execute 'osascript get.scpt arg1'. That should work (also
because I don't really need to get any data back from the script) but
it would be a bit more work to set up, and a bit slower to execute.
