%X Schoenberg once proposed a problem on the existence and uniqueness of bo-unded cubic splines interpolating at a biinfinite knot sequence. Carl de Boor gave a sufficientcondition so that he solved part of the problem. This article made an improvment on Boor'sresult by giving a sufficient and necessary condition. Thus we have completely solved the pro-blem that Schoenberg proposed.
