          The desired channels may be given instead as an
          immediate argument to TVON.  In that case, the
          channel specification is a BINARY mask of the desired
          channels.  Example:  TVON(13) will turn on TV channels
          1, 3, and 4 (values 1, 4, 8).

HELP SECTION

TVON
Type: verb
Use:  Turn on (enable) one or all colors on one or more gray-scale
      image channels on TV.  Does not affect status (on or off) of
      colors or channels not specified.

      Note that, if TVON is used in a FOR or WHILE loop or in an
      IF-THEN-ELSE construct, then the immediate argument is required.
      Otherwise, some item necessary to the loop/construct will be
      taken as the immediate argument.

Adverbs: TVON takes an immediate argument specifying in BINARY code
         which channels to turn on.  E.g. TVON(43) enables channels 1,
         2, 4, and 6 (values 1 + 2 + 8 + 32 = 43).

  COLORS.....Specifies which colors to enable.  0 = all, 1 = red,
                2 = green, and 3 = blue.
  TVCHAN,,...TV channel to turn on.  Only used if immediate argument
             is omitted and specifies a single value.  0 -> 1.
