A Method for Extending FORTRAN V for the Interactive Graphical Solution of Numerical Problems

Interactive computer graphics offers much in the way of bringing the program user closer to the problem solving algorithm. Techniques may be employed which provide for the execution of the program to be monitored and action taken to help the program find the solution, or to find it more quickly. Logic for handling breakdowns in the algorithm, much of which would not normally be coded into the program, may be economically employed, provided means are available to implement these techniques in existing FORTRAN programs. The paper is the result of a first step toward providing these means.
