     NAME

          circf - draws a filled circle


     SPECIFICATION

                    Scoord x, y, radius;




          FORTRAN   subroutine circf(x, y, radius)

                    real x, y, radius


                    subroutine circfi(x, y, radius)

                    integer*4 x, y, radius


                    subroutine circfs(x, y, radius)

                    integer*2 x, y, radius


     DESCRIPTION

          circf draws a filled circle, using the current color,

          writemask, and pattern. The circle has its center at (x,y)

          and a radius (radius), which are both specified in world

          coordinates.  Since a circle is a 2-D, these routines have

          only 2-D forms (note that circles rotated outside of the 2-D

          x-y planes appear as ellipses).  The circle is drawn in the

          x-y plane, with z=0.
