An application of Symanzik's method for treating exceptional momenta (the Callan-Symanzik equations combined with operator-product expansions) yields the leading corrections to the large-momentum behavior of the correlation function near the critical point. The result is used to argue that the conclusion drawn from numerical calculations, namely, that strong scaling is violated, is unwarranted.
