This operation is really just a shortcut for accessing a symbol called "PPAR" from the current directory. The PPAR symbol is used to store plot parameters and its contents is a five element list of the following items:

  1. The bottom left point (plot minimum) in X/Y coordinates expressed as a complex number. The default value is (-6.8, -1.5).
  2. The upper right point (plot maximum) in X/Y coordinates expressed as a complex number. The default value is (6.8, 1.5).
  3. The independent (X) variable to use when calculating points to plot from the equation. This item should be a symbol and its default value is "constant".
  4. The resolution of the plot expressed as a real value. It specifies the number of pixels in the plot view to increment by when calculating the next point. The default value is 1. Increasing this value will result in higher performance since fewer points need to be calculated but less accuracy in the plot.
  5. The position of the X/Y axes, specified as a complex number. The default value is (0,0).

When executed, this operation pushes the current value of PPAR onto the stack. If the PPAR variable is not set, an undefined name error is raised.
