Abstract: This package contains six TTY plotter programs as described below.

1. FTNPLT (Functional Plotter) allows the user to define the function Y = f(X) in a manner similar to that used in high school algebra.
2. RELPLT (Relational Plotter) will plot any relation defined in terms of X and Y. The relation must be defined in the form 0 = R(X, Y).
3. MULPLT (Multiple Relational Plotter) allows the simultaneous plotting of a maximum of 5 relations in the same section of the coordinate plane.
4. PRAPLT (Parametric Relational Plotter) allows the plotting of a relation 0 = R(X, Y) where the X and Y are themselves defined in terms of the parametric variable A.
5. POLPLT (Polar Coordinate Plotter) will plot a function of the form Rho = f(Alpha) on a polar coordinate grid.
6. SURPLT (Surface Plotter) attempts to plot a "bird's eye view" of a surface defined by a function of the form Z = f(X, Y). The graph somewhat resembles a topological map, where the letters used in the graph indicate the relative "height" of the range. The output is not printed in three-dimensional perspective.
