I'm interested in using the "External Functions" hook into Mathematica
described in Appendix B.7.6 of the book (pg 585).  I'm working on a NeXT
under NeXT release 0.9. I found the necessary 'mathlink' modules and
have compiled the example in the Appendix.

What I don't know is how to get this executable and Mathematica communicating.
EG, what do I type in Mathematica to set this up? Does my new executable need
to be in a magic directory?

Any clarification would be appreciated.
