The format for these blocks is as follows:
N1 A__;
N2 A__Z__X__;

A Angle this word, determined in AMP by your system installer, defines the
angle of a linear path. This manual assumes that the A--word is used.
The angle is a positive value when measured counter-clockwise 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 a representation of the actual coordinates 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 can be as many as 4 program blocks between the two
QPP blocks; however, those blocks cannot 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 blocks, 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.
