FORTRAN
subroutine circ(x, y, radius)
real x, y, radius

subroutine circi(x, y, radius)
integer*4 x, y, radius

subroutine circs(x, y, radius)
integer*2 x, y, radius

DESCRIPTION

circ outlines a circle.  The circle has a center at point (x,y) and a radius (radius), which are specified in world coordinates.  Since a circle is two-dimensional, these routines have only two-dimensional forms.  The circle is in the x-y plane, with z=0.  It is drawn using the current color, linestyle, linewidth, and writemask.
