REMOVIE
Type:  Verb
Use:   To rerun a movie or portion of a movie previously loaded
       and run with TVMOVIE.  During the movie phase, the cursor
       X position controls the movie frame rate, button A starts
       or stops the movie, button B reverses the direction of
       the movie, button C stops the movie (if needed) and
       allows color or black and white enhancement, and button D
       exits.  While the movie is stopped, the cursor X position
       controls which frame is displayed.  During image enhance-
       ment, the cursor X position controls the intercept, the
       cursor Y position controls the slope, buttons A or B
       switch between color and black and white enhancement,
       button C reverses the sign of the slope (b & w only),
       and button D returns to the movie mode.
Adverbs:
  TVCHAN......Image channel to load with the first frame.
              Channels TVCHAN+1,... will be used as needed.
              0  =>  channel 1.
  BCHAN.......First frame to show (relative to the first
              frame in TVCHAN).  0 => 1.
  ECHAN.......Last frame to show (relative to the first
              frame in TVCHAN).  0 => all.
  DOCIRCLE....False (<= 0.0) means to reverse the direction of
              the movie each time it hits the end.  Else show
              BCHAN after showing ECHAN or the reverse.
  DOCENTER....If true (> 0), limit the TV window to the size
              needed to hold 1 frame zoomed only to a factor of
              FACTOR.  This is available only on workstations
              and can be used to make TVMOVIE run faster.
  FACTOR......The zoom multiplication factor: 1 => no zoom, 2 =>
              double (linearly) each pixel, 3, 4, 5, ... etc.
              FACTORs between 1 and the number of frames across
              the full screen are meaningful.
