There is a function in common lisp called RUN-PROGRAM in Sun Common Lisp.
First of all, has anyone ever heard of it? Secondly, what does this
function do? And lastly, what is its counterpart in kcl. I know for sure
that my version of kcl does not support it.
Another thing that I would like to know is about the -load option of invoking
common lisp. In common lisp, you can invoke lisp by an option -load <filename>
which will load a given file into the interpreter before getting into it. I
was wondering what its counterpart in kcl is. I know (again) for sure that
my version of kcl does not do anything for -load or -l.
Thanks in advance for the help.

This isn't a Common Lisp function, it's a Lucid extension.

It runs a normal Unix program, as if you'd executed it from the shell. It
can optionally connect the input and/or output streams of the program to
Lisp streams. It's fully documented in the Working Beyond the Lisp
Environment section of the Advanced User's Guide chapter of the manual.

There probably isn't a direct counterpart in KCL, since KCL doesn't provide
many extensions to CL. The closest thing is probably calling the Unix
execlp(3) function.

Common Lisp doesn't specify anything about how Lisp is started, let alone
comand line options. This is another Lucid extension. There may not be a
KCL facility like this.

There is a sort-of similar function in kcl called 'system'. I don't
think it is as good as the run-program in lucid, but it might be what
you need ... eg:
>(system "ls")
beef factory filesys.lsp plan user.o
cd.o features filesys.o user.lsp work-elements
0
>(help 'system)
-----------------------------------------------------------------------------
SYSTEM [Function]
Args: (string)
KCL specific: Executes a Shell command as if STRING is an input to the Shell.
Not all versions of KCL support this function.
-----------------------------------------------------------------------------
It works for me on akcl 1.605 for Unix and the current beta release
akcl for dos.

I haven't checked this in vanilla KCL but at least AKCL 1.609 supports the
following functions (one runs a process simply for its side-effect, the other
gets you a pipe, i.e., an i/o stream):
>(describe 'system) (describe 'run-process)
SYSTEM - external symbol in LISP package
-----------------------------------------------------------------------------
SYSTEM [Function]
SYSTEM
Function in LISP package:
Args: (string)
KCL specific: Executes a Shell command as if STRING is an input to the Shell.
Not all versions of KCL support this function.
-----------------------------------------------------------------------------
RUN-PROCESS - internal symbol in USER package RUN-PROCESS
Function in the SI package:
Args: (string)
Execute the command STRING in a subshell and return a two way stream
associated to this. Use si::fp-output-stream to get an associated
output stream or si::fp-input-stream.
Bugs: It does not properly deallocate everything,
so that it will fail if you call it too many times.

OK, For run-program counterpart in kcl I got the following two functions
to work with :
1] run-process - My version of kcl (1.599) does not support it.
2] exclp - I have not yet checked it.
As far as "system" is concerned, it will surely not work. I need a stream
for input and output. This is not possible with system.
About the -load option, I really need that, but do not know how to do
it. Solve the following problem for me :
I want to have some way of loading some file before I get into kcl.
Note that init.lsp will not work because that will always load the
same file. You can say that I can change the init.lsp file, but I
am calling kcl through another program using rsh, and at various
points in the program, I want different files to be loaded!
If the above makes sense, please reply.
