The package is calculating one-, two- and three-point functions both algebraically and numerically to all tensor cases. This program is written as a package for Maple.Contribution to Proceedings of International Conference on High energy physics and quantum field theory in Zvenigorod (1993)High Energy Physics - Phenomenologytext
