Though I haven't looked for the detailed BootROM version (more detailed
than "OpenFirmware 3") I did discover a way to see if a method exists.
It's FIND, and it takes a counted address (basically, pointer to string
and length of string).  I believe it returns:

	0 and some other value (I forget what) if the method
	doesn't exist

	1 and the method address if the method exists
	and is not immediate

	-1 and the method address if the method exists
	and is immediate

Unfortunately trying it with literal strings, as in

" words" find

never gave me any useful results.  I never used FORTH seriously, I only
played with various versions, and they were all pre-ANSI.  Any FORTH
people out there?

I also found a list of command editing keys.  Thank you IEEE and Apple!
See the message which I will post next.
