X-PLOR does not provide any direct graphical interfaces. Rather,
it produces files that contain lists of numbers or other
objects. Included in this
book are many examples of how to interpret information
from X-PLOR with Mathematica (Wolfram, 1991) and to produce
graphical illustrations. Mathematica version 2.0 or later is required.
Mathematica can be obtained from Wolfram Research, Inc. (100 Trade Center Drive, Champaign, IL 61820, USA; phone:
