William Ulrich's new book is "The Year 2000 Software Crisis" (Yourdon Press). It is a guide to solving the problems that will arise in the millennium when computer software will translate the two-digit shorthand '00 as 1900, not 2000. For companies world-wide this computer failure could lead to business failure. Ulrich is President of Tactical Strategy Group, Inc. and a strategic Year 2000 advisor for corporations and government agencies.
