Roland DXY-1300 Command Reference Manual page 40

Please note the following when using the Y command.
(1) When the m parameter is set to 0 or 1, failure to specify at least 3 pairs of coordinates will
result in an error.
(2) When the m parameter is set to 2 or 3, failure to specify at least 2 pairs of coordinates will
result in an error.
(3) Specifying points with the same, or extremely close coordinates, may result in a curve that
is not smooth.
(4) Specifying points whose coordinates are separated widely, by comparison with the coor
dinates specified just before, may result in a curve that is not smooth.
(5) Be careful when specifying coordinates that fail on or close to the boundary of the plotting
area. Any parts of the curve that extend beyond the plotting area will not be drawn.
(6) As shown below, specifying the same coordinate values immediately before and after a
parameter specification will result in an error.
