So I will.  

I am trying to take some common LISP code which has some very complex
algorithms and interface them to C.  The specifics:

LISP: compiled common LISP
OS: IRIX Unix System V, AIX 3.1.x , Sun OS 4.1
Machine: Silicon Graphics Personal Iris, IBM RS/6000, Sun 4, Sun 3
C compiler: C compiler which comes with the system.  ANSI C for RS/6000,
K&R for Sun and IRIS.

The type of calls that I would make:

main()
{
	Molecule x;
	int i;

	i = LISP_Molecular_weight_of(x);
}


All of the computation would be in LISP, the User Interface for the
program would be in C.  Hopefully this is enough.  If not, let me know.
