Here is a bit of applescript which tells Lisp to print "Hi there" on the

You can compile it as an appleScript applet and run and, provided the eval
server is running in MCL, it will execute the format statement:

        set s to "(format t " &  ascii character of 34 & "Hi There" & ascii
character of 34  & ")"

        tell application "MCL" to do script s

The method which I mentioned to you previously involving the "on" syntax
works for sending a raw appleevent of arbitrary type to some application
which does not support scripting ( but does support the event).  The "do
script" construct translates into an appleevent of type 'dosc' and should
be convenient for your needs.

In a sense the eval-server code makes MCL scriptable in that it will
execute any string which comes over in the direct param of an appleevent of
type dosc.  It really isn't scriptable of course, in the AppleEvent sense -
I'm not sure what terminology LISP would care to define (other than eval of

An open question is: if one built an application in MCL, defined the
application's terminology (in an AETE) and built the appropriate event
handlers, AETEResolve callbacks, would scripting then work?  I've never
tried this - anyone else?
