M
Function:
When M00
CR
is
input, the
pen moves from
the current point to the
origin
of
the absolute
coordinate system.
Example:
LPRINT "M00"
(0,
0)
Origin
X
(300,
-200)
Current point
Combining
P Mode
and
C Mode
When
changing
to the
P mode,
the current position of the pen becomes
the
origin
of
the Y-axis
(Y=0).
(In
the
C
mode,
the absolute coordinate value
in the
Y
direction
is
not
stored.)
Example:

LPRINT CHR$

LPRINT
"G01
X500 Y-500"

LPRINT
"G01 X1000 Y-500":
Note
regarding
line
30:
CHR$
(32)
is
a
space code; without
it,
letter
"A"
would
be
printed
right
on
the
point.
CHRS
(8) is
a
back-space code
to
compensate
for the
normal
movement
to the
right
caused
by
the space code and "A". The pen moves
twice (four or
eight
times)
in
an
enlarged
mode,
therefore use
the appropriate
number
of back-space codes
to
compensate.
