Even
when
the
X
and/or
Y
coordinate of the point
specified
is
not
present
on
a
circumference (determined
by
the current point
and
the center point
(I,
J)
)
the
pen
moves
to the
point
specified.
However,
when
both
coordinates
of
the point specified
are
outside the radius of the
circle,
the
pen
will
move
along
a
maximum
of
1-1/2
times the circumference
and
then
stop.
Under
this
condition, the
relative
relationship
between
the
Absolute coordinate
value
and
the
pen
position
will
be
lost.
Example
for
when
the point
specified
by
X,
Y
(U,
V)
is
not
present
on
the
circumference
(but
is
inside
the
radius
of
the
specified
circle):
LPRINT "G02 U-300 V-300

Example
for
when
both
coordinates
of
the point
specified are
outside the radius
of
the
circle
(shaded
areas):
LPRINT "G02

One
special
application
of
G02
(or
G03)
is
to
move
the coordinate
origin.
When "G02
X0 Y0"
(or
"G03
X0
Y0'')
is
executed, the current
pen
position
becomes
the
new
origin.
