The API reference doesn't mention the ability to execute a script
since that is a property of the language, and not the api reference
itself.
So it winds up being (after you have got the session running) a jset
followed by a jdo.
A trick, though, is that you'll have to use language features (13!:)
to support debugging of the code within your application. So that'll
be something like jdo("13!:0]1"); to enable debugging, jdo("13!:1''");
to get a readable stack trace, and so on...
Good luck,
