Abstract
We present a new method for treating the inner Cauchy boundary of a bl ack hole spacetime by matching to a characteristic evolution. We discu ss the advantages and disadvantages of such a scheme relative to Cauch y-only approaches. A prototype code, for the spherically symmetric col lapse of a self-gravitating scalar field, shows that matching performs at least as well as other approaches to handling the inner boundary.
