The easiest thing to do is to send "EVAL" events. The MCL "EVAL"
and "DOSC" handlers are implemented by the file "ccl:examples;eval-server.lisp".
The following comment is at the end of the file
"ccl:examples;appleevent-toolkit.lisp". This method will work
whenever you can cons up a string for MCL to read/eval/print.
To send more specialized events, you'll need to write an MCL handler
yourself.

; To communicate from HyperCard to MCL, try typing the following two lines
; to the message box (after loading the file "ccl:examples;eval-server").
;
;  request "(print (+ 1 2))" from program "MCL 2.0"
;  put it
;
; "3" will be printed in MCL's Listener and in HyperCard's message box.
