Location measured by distance from 0,0 in current UCS	#X,Y
Location measured by distance from last point	@X,Y
Location measured by distance and angle from 0,0 in current UCS	#distance<angle
Location measured by distance and angle from last point	@distance<angle
Location by extracting and combining coordinate values from 2 or 3 points	.x or.y or .xy etc
An angle override from current point	<angle
