TVCUBE
Type:  Verb
Use:   To load a number of subportions of planes of a cube into
       the TV memory and then to display them in sequence at
       user chosen rates (like a movie).  The verb can load up
       to NC TV memories with 64 61x61, 16 124x124, 4 250x250,
       or 1 510x510 planes of cube, where NC = #TV memories + 1
       - TVCHAN.  Thus, movies of as many as 256 spectral
       channels, for example, may be shown on a TV having 4
       memories.  TVs with larger screens (in pixels) can do
       more.  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 enhancement, 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.  Use REMOVIE to resume the
       movie display without reloading the images.  The verb
       TVMOVIE is similar to TVCUBE, but it loads the images in
       a pattern which is less pleasing to the eye when viewed
       altogether and more pleasing when viewed as a movie.
Adverbs:
  INNAME......Image name(name).       Standard defaults.
  INCLASS.....Image name(class).      Standard defaults.
  INSEQ.......Image name(seq. #).     0 => highest.
  INDISK......Disk drive # of image.  0 => any.
  TBLC........The Bottom Left-hand pixel of the subarray of
              the map to be displayed. The value (0,0,...)
              means take the entire image up to TTRC.
  TTRC........The Top Right-hand pixel of the subarray of
              the map to be displayed.  The value (0,0,...)
              means take the entire image from TBLC.
  TXINC.......Load every TXINC'th column beginning at TBLC.
  TYINC.......Load every TYINC'th row beginning at TBLC.
  TZINC.......Load every TZINC'th plane beginning at TBLC.
  TVCHAN......Image channel to load with the first frame.
              Channels TVCHAN+1,... will be used as needed.
              0  =>  channel 1.
  DOALL.......<= 0 -> find the first axis > 2 with multiple pixels
                      (after application of TBLC and TTRC) and loop
                      over those pixels included.
              >  0 -> find all axes > 2 with multiple pixels (after
                      application of TBLC and TTRC) and loop over
                      all pixels included.
  PIXRANGE....Min,Max intensity to display. 0 => entire range.
  FUNCTYPE....Image intensity transfer function
              'LN' => linear;        'NE' => negative lin.
              'LG' => log;           'NG' => negative log;
              'L2' => extreme log;   'N2' => negative extra log;
              'SQ' => square root,;  'NQ' => negative square root;
              others => linear.
  LTYPE.......A label is place in the upper left corner of each
              frame if LTYPE > 2.  Labelling type, see HELP LTYPE for
              details:  3 or 7 = standard, 4 or 8 = relative to ref.
              pixel, 5 or 9 = relative to subimage (BLC, TRC) center,
              6 or 10 = pixels.  7-10 all labels other than tick
              numbers and axis type are omitted.  Add n * 100 to alter
              the metric scaling.
              TVCUBE has very limited space for labels and may not
              honor your LTYPE.
              If DOALL > 0 and there are in fact multiple axes over
              which the task loops, the labels will be simple plane
              number (over all planes not just TBLC-TTRC/ZINC).
  DOCIRCLE....False (<= 0.0) means to reverse the direction of
              the movie each time it hits the end.
  DOPOS.......True (DOPOS(1,1) > 0.) means put a pointer in
              each frame to show how far through the movie that
              frame is.
  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.
