FOVAL_ARC()                                                         G_EXAM07
   Draws an elliptical arc with a given center and radius.

   Syntax
         FOVAL_ARC(nX,nY,nXRadius,nYRadius,nStartAngle,nAngleWidth,nColor)

   Arguments
         nX             Absolute horizontal screen position.
         nY             Absolute vertical screen position.
         nXRadius       X axis length.
         nYRadius       Y axis length.
         nStartAngle    Starting angle in tenths of degrees. (0-3600)
         nAngleWidth    Angle width in tenths of degrees. (0-3600)
         nColor         Palette color number. (0-15)

   Returns
         None

   Note: ATX() and ATY() can be used to position the elliptical arc.

   Description
         FOVAL_ARC() draws an elliptical arc centered at nX,nY. The nXradius
         and nYradius is assumed positive and along the X-axis.

         nStartAngle defines the start of the arc and nAngleWidth sets the
         length of the arc. Both values specify angles using tenths of a
         degree, ranging from 0 to 3600 rotating in a counter-clockwise
         direction.

         FLP_CAP can be used in place of nX,nY to draw the arc at the current
         active point.
