special value for line drawing routines

Ncarg-folks,

I am drawing a zonal average line on my plot page along the
side of my xy plot with the routine 'curved'. However, there
are times when I don't want points plotted in the line, for
example, when there is all land points in the zonal average at
the South Pole.

Is there a 'special value' that I can set like SPV for the
Conpack package? I'd rather not have to go through a do loop
and plot the line one point at a time.

Thanks,
