STYLE(drawStyle1, Draw) { type = Ellipse; back = gold; col = white; width = 20; currel=TC; }
STYLE(drawStyle2, Draw) { type = Ellipse; back = \\006400; col = \\000000; width = 2; currel=CC; }
STYLE(drawStyle3, Draw) { type = Ellipse; back = blue; col = navy; width = 6; currel=CR; }

PAGE(pageName, pageStyle)
{
POSN(70, 150);
DRAW(ellipse1, 120, drawStyle1);
POSN(240, 136);
DRAW(ellipse2, 250, 100, drawStyle2);
DRAW(ellipse3, 100, 150, drawStyle3, 470, 120);
}
