        [GREG1\]CURVE  [Array_X  Array_Y]  [/ACCURACY  A]  [/VARIABLE V [Ar-
    ray_V]] [/PERIODIC] [/BLANKING Bval Eval]

    Builds the spline interpolation of the (X,Y) pairs read  by  COLUMN,  or
    stored  in  the  variables Array_X Array_Y, using the selected algorithm
    and options. The current pen with its dashed pattern is used.  Presently
    the  only  algorithm  available is CUBIC_SPLINE. By default, the command
    assumes that a curve Y=f(X) is to be plotted ; this can be changed using
    options to specify the kind of curve to be plotted.
