SETCO

       SUBROUTINE  SETCO (COLOR)
 C$    (Set Color)
 C$    Define the  index  of  the color  required  for  subsequent
 C$    plotting, where "COLOR" is an integer in the range  0..255,
 C$    as follows:
 C$
 C$    Index  Color   (R G B)
 C$    =====  =====   =======
 C$      0    Black   (0 0 0), or default for device
 C$      1    Red     (1 0 0)
 C$      2    Green   (0 1 0)
 C$      3    Yellow  (1 1 0)
 C$      4    Blue    (0 0 1)
 C$      5    Magenta (1 0 1)
 C$      6    Cyan    (0 1 1)
 C$      7    White   (1 1 1), or complement of the default.
 C$    8..255 Index into the device-dependent color table.
 C$
 C$    Color indices 8..255  if selected must  be predefined by  a
 C$    call to SETCI (Set Color  Index).  The color index will  be
 C$    ignored for those devices which do not provide color.
 C$
 C$    Some devices specify color  with the subtractive  primaries
 C$    cyan,  magenta,  and  yellow,  rather  than  the   additive
 C$    primaries, red, green, and blue.  The relationship  between
 C$    the two is simple: (C M Y) = (1 1 1) - (R G B).
