SPECIFIED END POINT
ACTUAL END POINT
Note: The MOVECIRC computes the radius and the total angle of rotation
from the centre, and end-point. If the end point is not on the calculated path,
the move simply ends at the computed end and not the specified end point. It
is the responsibility of the programmer to ensure that the two points corre-
spond to correct points on a circle.
Note: Neither axis may cross the set absolute repeat distance REP_DIST dur-
ing a MOVECIRC. Doing so may cause one or both axis to jump or for
their FE value to exceed FE_LIMIT.

Example The following command sequence plots the letter O:
MOVE(0,6) ' Move A -> B
MOVECIRC(3,3,3,0,1) ' Move B -> C
MOVE(2,0) ' Move C -> D
MOVECIRC(3,-3,0,-3,1) ' Move D -> E
MOVE(0,-6) ' Move E -> F
MOVECIRC(-3,-3,-3,0,1) ' Move F -> G
MOVE(-2,0) ' Move G -> H
MOVECIRC(-3,3,0,3,1) ' Move H -> A
