The decay constants of the heavy-light pseudoscalar mesons are studied in a
high statistics run using the Wilson action at β=6.0 and β=6.2, and
the clover action at β=6.0. The systematics of O(a) discretisation
errors are discussed. Our best estimates of the decay constants are: fD​ =
218(9) MeV, fD​/fDs​ = 1.11(1) and we obtain preliminary values for fB​.Comment: at the Dallas Lattice Conference, October 1993. 3 pages in a single
