  abstract =     "A system is presented to allow end users to solve
                 nonlinear differential equations without need to write
                 computer programs. The system treats $n$th order space
                 (one dimensional), first order time systems with
                 initial and/or two point boundary value specification.
                 Users of the system need only enter the problem in
                 direct mathematical notation, and output is
                 automatically presented as a solution graph. The system
                 allows the user to alter this equations, in-situ, that
                 is to computationally steer his model. Thus the system
                 is suited for model prototyping. Implementation is
                 based on an object-oriented paradigm, well established
                 and robust numerical procedures, and distributed
                 computing to supported needed resources for numerically
                 intensive tasks.",
