Tony, thanks for the info. But why do I need to go to forth for
this? why cant someone show me how to hand compile the jmc.pdf
into an assembly code like L. Peter Deutsch, a 13-15 year old
kid wrote and PUBLISHED as the first author, making money from
the ARPA grant because his father worked in the area and he
had the connections to get the info from the place where it was
discovered. I suspect they thought that the kid is safer and
less competitive than some grown up to share the info.

It's not that you need to go to FORTH - it's that the techniques so 
lucidly explained by Richard Jones in his essay 
(http://www.annexia.org/_file/jonesforth.s.txt) generalise with *very* 
few modifications to implementing Scheme. I encourage you to read the 
essay. I believe that if you do so, you will start to see the 
relationship between the very low level and the very high level that you 
are interested in.

You will need not very much more assembly to build (the kernel of) a 
Scheme than to build (the kernel of) a FORTH.

Regards,
   Tony

Your question is not unlike that of that young man who, be it truth or
legend, wrote to composer Wolfgang A. Mozart, asking for advice about
how to get started in writing symphonies. Mozart replied that a
symphony is a complex musical form, and that one should start by
writing simpler works and work his way up over years. The man
objected, "But Herr Mozart, you were already writing symphonies when
you were eight years old!" To which Mozart replied, "Indeed, but I
didn't have to ask how."

Like young Mozart, Peter Deutsch probably didn't have to ask how. He
may have had access to equipment and people through his father, but
ultimately he did the grunt work of taking a high level program as a
specification of behavior, and writing the corresponding assembly
program.
