  Studies of the physics potential of the Future Linear Collider are
establishing a broad programme which will start in the region of 350 to 500 GeV
C. of M. energy. The main goal is to understand why the standard model works;
by studying the properties of the Higgs sector, if it is within reach, and by
exploring the complex world of Supersymmetry, if it is real. If the Higgs boson
is not found soon, then the Linear Collider can test the standard model with
high precision measurements, both at energies approaching 1 TeV and with high
statistics at the Z0.
