HELP SECTION

TVSTAR
Type: Verb
Use:  TVSTAR will plot "star" positions from an ST extension
      file for an image on the TV.  If there is more than one
      image (of a map) visible on the TV, the routine will ask
      the user to position the cursor on any part of the image
      he wishes starred and then to press any button.
      Note that the image used to load the TV must have an ST
      extension file (produced by STARS) before TVSTAR may be
      run.
Adverbs:
  INVERS......Version number of ST (star position) file to be
              used to plot star positions as plus signs.
              0 => highest.
  STFACTOR....Scale factor used to multiply star sizes in file
              for plotting. > 0 => scale star size
                            = 0 => 1
                            < 0 => scale by abs(STFACTOR) and
                                   show any star label
  GRCHAN......Graphics channel (1 - 7) to use for line drawing.
              0 => 2.
