I was also writing about C, which doesn't have a select function in
any implementation I've used. Is this a Unix feature? This is an
important question to me, as the people likely to employ me are
more likely to not use Unix. I'd rather use Lisp than C, but I have
no choice about that, except in my own time and with my own money.
The Lisp Machine idea is a good one, and shouldn't be held back
by OS issues. Ideally, the OS should be in Lisp. To quote a certain
source of influenctial ideas: "A operating system is a collection
of things that don't belong in a language. There shouldn't be one."
That's a purist's approach, and I felt that way 10 years ago. Now,
I bow humbly before the alter of the real world, but I'm not happy.
After playing with a pure OOP language, I found a great deal of
disgust and contempt for it by most programmers, as it couldn't
produce images as small as C. As usual, they were comparing the
"Hello, World" type of program, which is not an app, therefore
not a real test.
It makes no difference to these people. They claim they're living
in the real world, and I won't argue with them, or evangelise.
10 years ago, I also wanted to use Unix. It's been a long wait,
and it's far from over. Oh dear, this is becoming another rant...

Lisp Machine style, the OS was not only written in Lisp, it was part
of a single Lisp system.
I do agree that most current OS isolate processes and users too much
from one another, but I think the Lisp Machine isolated them too
little.

I have two questions about AKCL(or KCL):
(1) How to compile LISP code in AKCL. What I am doing is using
"COMPILE-FILE" to get object file. And then load the object file
into AKCL interpretor to execute it. For example, if the source code
is in file "foo.lsp", I do the following:
>(compile-file "foo.lsp")
>(load "foo.o")
Then execute the function in foo.o in AKCL interpretor.
Can I compile the source file to get a executable file directly
without having to load it into the interpretor for execution?
(2) I am writing a big program in C. Some functions can be better
implemented in LISP. Can I call compiled AKCL functions from C code?
How to do it?
Thanks.

Simple answer :
Call (si:save-system "xyz") after loading foo.o. (This terminates AKCL !)
The saved image "xyz" contains all loaded code. Compiled code alone is
not enough to run a program since the run time library is necessary.

I suppose you have to use the AKCL as a frame and then load the C-code into it.
(The manual describes this decently).
The other way (loading AKCL into a running C-program) probably will fail.
Of course, if you have all sources of AKCL, you can rebuild it linking it
together with the C program.

Thank you for the help.
I still have a question:
If I have a function foo in the file foo.lsp like the following.
(defun foo () ... )
I want to start the execution of function foo immediately after I
enter xyz under UNIX environment. How can I achieve that?
At present, after typing xyz, I am in KCL. I have to type (foo) to
start executing the function.

Say
(setq si::*top-level-hook* 'foo)
just before you save the image.
KCL documentation follows:
Documentation:
*TOP-LEVEL-HOOK*
Variable in the SI package:
If this variable has a function as its value at start up time, then
it is run immediately after the init.lsp file is loaded. This is useful
for starting up an alternate top level loop.
This is an alternative:
Documentation:
TOP-LEVEL
Function in SI package:
Args: ()
KCL specific: Starts the standard top-level listner of KCL. When the KCL
process is invoked, it calls SI:TOP-LEVEL by (FUNCALL 'SI:TOP-LEVEL).
To change the top-level of KCL, redefine SI:TOP-LEVEL and save the core
image in a file. When the saved imange is invoked, it will start the
redefined top-level.
