This operation takes a symbol from the top of the stack. The symbol specifies the "independent variable" to use when plotting the equation which was specified with STEQ. The independent variable is calculated for each point along the X axis. The value of the equation is plotted on the Y axis.

The independent variable is stored in the plot parameters, found in a variable called PPAR in the current directory. The existing independent variable which may be specified in an existing PPAR symbol will be changed and then PPAR is stored, replacing the old value. If PPAR did not exist prior to executing these operations, a new PPAR symbol is created. Its contents will be defaults except for the independent variable which is specified from the stack.
