I have written to short C-program to calculate all nonbonding forces
between a macromolecule and a ligand. The force are calculated 
according to the old Amber force field parameter (Weiner 1986). 
Currently only Coulomb and van der Waals forces are calculated, 
the hydrogen bond term which should replace the van der Waals term 
in some cases is ignored. Coordinates are read from an Insight

If you are interested I can send you the source code.
