I believe the following snippet from the G%20Codes.html page on the site is
dodgy. Alternatively, I am seriously not understanding something. E.g. I
cannot figure out a reason why from Z0, (on the first line) you get to Z=9 via
a Z-1 command on the second line.
I just thought I would let the documentation maintainers know about it, for
when they do their next corrections run.
[ Not a complaint, just trying to be helpful]

G2 Example Line
G0 X0 Y0 Z0
G17 G2 X10 Y16 I3 J4 Z-1 (helix arc with Z added)
P word Example
G0 X0 Y0 Z0
G2 X0 Y1 Z-1 I1 J0.5 P2 F25
The above example line will make a clockwise (as viewed from the positive
Z-axis) circular or helical arc whose axis is parallel to the Z-axis, ending
where X=10, Y=16, and Z=9, with its center offset in the X direction by 3 units
from the current X location and offset in the Y direction by 4 units from the
current Y location. If the current location has X=7, Y=7 at the outset, the
center will be at X=10, Y=11. If the starting value of Z is 9, this is a
circular arc; otherwise it is a helical arc. The radius of this arc would be 5.
