    "abstract": "This paper describes a user-friendly frontend to a Fortran program that\nintegrates coupled nonlinear ordinary differential equations. The user\ninterface is built using the NeXTstep Interface Builder, together with a\npublic-domain graphical palette for displaying intermediate and final results.\nIn running the code for a given set of equation parameters the user sees a plot\nof the solutions at each stage of the iterative process. In the case of a\nsuccessful sequence of iterations, the initially discontinuous curves smooth\nout as the scale parameters of the solutions are adjusted to achieve a solution\nto the nonlinear equations. If the iterative process goes astray, as it often\ndoes for a poor choice of starting scale parameters, the user has the\nopportunity to stop and start over with a better choice, guided by the result\nof the previous run. The ease of interaction with the equations also allows the\nuser to develop an intuition regarding their solutions and to explore the\nparameter space for the equations much more quickly.",
