Sorry, no.  The source code for the compiler, written in c I think, is available
ftp://ftp.cs.orst.edu/pub/budd/ReadMe.html.  I could check-out the book and
reproduce some of the pages, but I'm not sure that'd be legal.  I've got some
code in c++ which does what Budd suggested in c++ classes.  Unfortunately,
I have'nt looked at it in years; so I don't know if it'll still compile.  It may
give you some idea of Budd's design, but I still think you'd have to look at the
book to appreciate it.  I Bcc'ed Budd in my original post; so, maybe he'll  have
time and inclination to help.  I'd also be happy to supply what code I have that
implements his ideas in c++ classes.
