DOCIRCLE
Type: Adverb   (logical,  > 0  =>  true)
Use:  If True, do some operation in a "circular" manner, if
      false do it in a linear manner.
Null Value:  False  (-1)
Verbs:
   REMOVIE.....Rerun a previously loaded movie (as TVMOVIE).
   TVCUBE......Verb to load a cube into tv channel(s) & run a movie.
               DOCIRCLE used as in TVMOVIE.
   TVHUEINT....Make a hue/intensity display from 2 TV channels.
               DOCIRCLE differentiates between a circular set of colors
               (blue -> red -> blue) and a linear color spectrum (blue
               -> red only).
   TVLABEL.....Label a TV image.  DOCIRCLE controls whether the ticks
               are drawn as short lines (false) or as a full coordinate
               grid (true).
   TVMOVIE.....Load a cube into TV channel(s) and run a movie.  DOCIRCLE
               true causes the movie to be an infinite loop and false
               causes the movie to reverse direction at each end.
Procedures:
   CIRCLEVS....Sets RGBLEVS to fill LEVS with a circular color scheme.
               DOCIRCLE true does a full circle of colors, false does
               only blue to red.
Tasks:
   CCNTR.......Generate a contour plot file from an image with CC or MF
               plotted.  DOCIRCLE used as in TVLABEL.
   CNTR........Plot a contour representation of an image; as TVLABEL.
   CONPL.......Plots AIPS gridding convolution functions; as TVLABEL.
   DFTPL.......Plots DFT of a UV data set at arbitrary point versus
               time; as TVLABEL.
   GREYS.......Plot a grey-scale representation of an image.
               DOCIRCLE used as in TVLABEL.
   HUINT.......Make RGB image from images of intensity & hue, like
               TVHUEINT; used as in TVLABEL.
   KNTR........Make a contour/grey plot file from an image w multiple
               panels; used as in TVLABEL.
   PCNTR.......Plot a contour plus vector representation of an
               image.  DOCIRCLE used as in TVLABEL.
   PFPL1.......Paraform Task to generate a plot file: (does grey scale);
               DOCURCLE used as in TVLABEL.
   PLAYR.......Task to load one or two images and play with them on the
               TV; as in TVLABEL.
   PROFL.......Plot a perspective representation of an image.
               DOCIRCLE used as in TVLABEL.
   TVHUI.......Make TV image from images of intensity, hue, saturation.
               DOCIRCLE true plots with a full circle of hues, false
               uses only blue to red.
