LISP & FORTH ... in some ways LISP is the self-hosting high level
language and FORTH is the self-hosting low level language.  I suggest
reading:

  (grab the tarball and fish out the files ci86.lina.asm & .html)

The concept of indirect threaded code isn't explained well anywhere,
but once you "get it" you'll understand how the code in ^^ is
implemented.

And:

I'm still playing with my FORTH, trying to get it down to something
elegant -- the minimum amount of assembler, but without being so
minimal as to be confusing.  Then I'll put it up on my site.
