By a Tangential Line, a Point on the Circumference and Radius
General syntax is
<Symbol> = CIRCLE/TANTO, line1, {XSMALL/ XLARGE / YSMALL / YLARGE}, point1, RADIUS, radius1
These modifiers specify the choice of the circle whose centre has algebraically larger or smaller X or Y co-ordinate with reference to the point.
C1 = CIRCLE / TANTO, L1, XLARGE, P1, RADIUS, 26
C2 = CIRCLE / TANTO, L1, XSMALL, P1, RADIUS, 26
C3 = CIRCLE / TANTO, L1, YLARGE, P2, RADIUS, 26
C4 = CIRCLE / TANTO, L1, YSMALL, P2, RADIUS, 26
