#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
