We set out the main features of Maple V, Release 3, and discuss its potential value to econometricians. Computer algebra systems, of which Maple is a leading example, have developed with the increased power of modern computers, but require skill and patience to use. It seems likely they will find a place in the econometrician's toolkit for work at the interface between analytic and numerical work, where they should prove valuable. However, although Maple has many of the features of conventional statistical/econometric/numerical software, it should not be seen as a substitute. Copyright 1995 by John Wiley & Sons, Ltd.
