DODARK
Type:     Adverb   (Scalar - generally logical)
Use:      Plot programs are able to draw "dark" as well as "bright"
          vectors.  The dark ones are normally drawn to provide
          contrast when the background grey-scale image is strong.
          DODARK is used to control whether the dark vectors are drawn
          in a different color than the corresponding bright vectors.
          When writing to the TV with DODARK > 0, the dark vectors
          are drawn in the black overlay graphics channels.  When
          writing to a plot file, darks vectors are just a different
          operation code than bright vectors.
Tasks:
  GREYS.......Make a grey-scale plot with contours.  DODARK functions
              only when DOTV > 0.
  KNTR........Make a grey-scale, contour, and polarization vector
              plot with multiple panels.  DODARK functions only when
              DOTV > 0.
  LWPLA.......Convert a plot file to PostScript for saving and/or
              printing.  DODARK > 0 makes dark vectors appear black
              (actually PLCOLORS(1,5)-PLCOLORS(3,8)).  You may want
              DODARK false when making color vectors and/or coloring
              the image.
  PCNTR.......Make a grey-scale, contour, and polarization vector
              plot.  DODARK functions only when DOTV > 0.
  TVPL........Display a plot file on the TV.
