The book you refered to was (I think) "Threaded Interpretive Languages" but
can remember the name.  Another userful one for you might be Stack Machines (I
think) by Phil Koopman (I think).

I have written an automotive engine analyzer, but I've never written a paper
about it (confidentiality problems).  There is also one written for deisal
locomotive engines that was written up in one of the Rochester Forth
Conferences.  Can't remember the year, but it was quite some time ago.  I'm
not sure how to answer the question about what it was like.  It was a monster
program, with too many decision points to test.  On average, mine found the
correct answer about 70% of the time which was better than the average
mechanic could do consistantly.  So, the system is still very succesful in the
marketplace.  The company that uses it is still very successful.

FIG sells them, but I have no idea if any library carries them.

Sorry I can't be more help, but am on vacation and don't have all my reference
sources with me.
