The format for these blocks is:
N1 ,A__;
N2 ,A__Z__X__;
Where : Is :
,A Angle This word is used to define the angle of a tool path. This manual
assumes that the ,A-word is used. The angle is a positive value when
measured counterclockwise from the first axis defining the currently
active plane and a negative value when measured clockwise. The
angle is in units of degrees.
ZX End Point of
second block These represent the actual coordinate location of the end point of the
second block. They must be programmed as absolute values and
must be axes in the current plane.
Important: There may be up to four program blocks between the two
blocks in the above format. The only requirement being that these blocks
may not generate axis motion in the current plane.
Both of these blocks must be programmed in the same plane. If the current
plane is changed between these two blocks execution, the control generates
an error.

If the control cannot determine an intersection point for the two linear
paths (for example, if the paths are parallel), an error occurs.
