z
No Parameters — Sets P1 and P2 to their default locations,
adjusted by any current axis rotation.
Note If an IP command without parameters is executed after the axes
are rotated with the RO command, P1 and P2 locations change to
reflect the rotation. If the coordinate system orientation subsequently
changes (e.g., by sending an RO command), the plotter unit position
is maintained with respect to the new orientation.
z X,Y Coordinates — Specify the location of P1 (and, optionally,
P2) in plotter units. Specifying P2 is not required. If P2 is not
specified, P2 tracks P1 and its coordinates change so that the
X,Y distances between P2 and P1 stay the same. This tracking
process can locate P2 outside the effective window. Used
carefully, the tracking function can be useful for preparing more
than one equal-sized drawing on a page. For an example, refer to
“Drawing Equal-Sized Pictures on a Page” earlier in this chapter.
z Neither X,Y coordinate of P1 can equal the corresponding
coordinate of P2. If either coordinate of P1 equals the corres-
ponding coordinate of P2, the coordinate of P2 is incremented
by 1 plotter unit.
The locations of P1 and P2 interact with the following commands:
