FUNCTION  SetHTTxtColor(ColorString)    Set the HelpTopic window text colors

     Both the SetHTWinColor() and SetHTTxtColor() functions are used
to change the default help topic window colors.  The SetHTWinColor()
will set the default window colors using the standard SETCOLOR color
codes for compatibility.  The order of the color fields are as
follows:

          Standard       All screen output commands and functions
          Enhanced       GETs and selection highlights
          Border         Border around screen, not supported on EGA and VGA
          Background     Not supported
          Unselected     Unselected GETs

     See your Clipper reference manual or Norton Guides file for a
reference of valid colors.

     The SetHTTxtColor() function will change the colors with-in the
help topic window.  This color will be used from then on until the
next SetHTWinColor() or SetHTTxtColor() function call.
