     I'm trying to write a simple program in Multi-Forth to replace the 
annoying flash generated by DisplayBeep with an audio bell instead.  My
idea is to use SetFunction to replace the DisplayBeep jump vector in the
Intuition library with one to my own code. 
     SetFunction requires the absolute address of the replacement routine.
How do I get this address?  Even if I use the FROM.HEAP word to request heap
space for my routine, how do I tell Multi-Forth to compile my Forth code
at the address returned by FROM.HEAP?  Will this approach even work, or 
should I be thinking along different lines?
     Thanks in advance for any help.
