We describe a first attempt to calculate scalar 2-loop box-functions witharbitrary internal masses, applying a novel method proposed in hep-ph/9407234.Four of the eight integrals are accessible to integration by means of theresidue theorem, leaving a rational function in the remaining variables. Theresult of the procedure is a three- or sometimes two-dimensional integralrepresentation over a finite volume that can be further evaluated usingnumerical methods.Comment: 10 pages, LaTeX2e, 11 eps-figures, needs epsfig.st
