Abstract
We discuss methods and techniques that were recently used in the follo wing high order perturbative calculations: the large quark mass expans ion of the decay rates Z(0) --> hadrons and tau --> nu+ hadrons and th e calculation of various quantities for deep inelastic lepton hadron s cattering. Progress on the automatization of some general procedures i s discussed.
