In
modes 0, 1,
and
2 this escape sequence moves the screen window to
the
posi-
tion occupied by the cursor. This sequence does nothing
if
executed
in
mode
3. The screen window
is
positioned so
that
the cursor
is
located near its centre.

This escape sequence defines those characters corresponding
to
ASCII codes
224 (&HEO)
to
254 (&HFE). This sequence consists
of
eleven bytes as follows:

Byte 9:

Byte 10:

row 7
Byte
11:
Pattern
for dot row 8
The pattern making
up
each dot row
is
specified as the ASCII code equivalent
of
the binary number whose" 1 " bits correspond
to
dots which are turned on,
and
whose
"0"
bits correspond
to
dots which are turned off.
For
example,
specifying
63
(where
63
is the decimal equivalent
of
0011111lB) for byte 4 causes
all dots in
dot
row one
to
be turned
on
when
the
character code specified in
byte 3 is displayed; conversely, specifying 0 (00000000) causes all dots in the
applicable row
to
be turned off.
A sample definition for character code 230 is shown below:
