     The _selectpalette function works only under the video modes
     _MRES4COLOR, _MRESNOCOLOR, and _ORESCOLOR. A CGA palette consists
     of a selectable background color (Color 0) and three set colors.
     Under the _MRES4COLOR mode, the <number> argument selects one of
     the four predefined palettes shown below:
 
     _MRES4COLOR Palette Colors
 
               -------------- Color Index --------------
     Palette
     Number    Color 1       Color 2         Color 3
 
     0         Green         Red             Brown
     1         Cyan          Magenta         White
     2         Light green   Light red       Yellow
     3         Light cyan    Light magenta   Bright white
 
     The _MRESNOCOLOR graphics mode is normally used with
     black-and-white composite monitors, with palettes consisting of
     shades of gray. This mode will produce color when used with a
     color monitor. The number of different palettes available depends
     on whether CGA or EGA hardware is used. With a CGA configuration,
     the two different palettes shown in the table below are
     available. Note that although four palette numbers are listed,
     palettes 0 and 1 are identical, as are palettes 2 and 3.

     2         Light Blue     Light Red     Bright White
     3         Light Blue     Light Red     Bright White
 
     With an EGA, the three different palettes shown in the table
     below are available in the _MRESNOCOLOR video mode. Note that
     although four palette numbers are listed, palettes 1 and 3 are
     identical.

     3         Cyan            Magenta       White
 
     You can use the _ORESCOLOR high-resolution video mode for the
     Olivetti graphics adapters found in most Olivetti computers and
     in the AT&T 6300 series computers. In _ORESCOLOR mode, an
     argument number in the range 0-15 selects one of the colors
     listed below. The background color is always black in this mode.
 
     _ORESCOLOR Mode Colors
 
     Index   Color        Index   Color
 
     0       Black        8       Dark Gray
