to specify the dots in one vertical column of dots, the LQ expects

An example character definition program should make this clear:
10 LPRINT CHR$(27)"x0"
20 LPRINT CHR$(27)"&"CHR$(0);
30
LPRINT "@@";
40
LPRINT CHR$(1)CHR$(9)CHR$(l);
50 FOR I=1 TO 27
60 READ A: LPRINT CHR$(A);
70
NEXT I
80 LPRINT "@@@@@"
90 LPRINT CHR$(27)"%"CHR$(l);
100 LPRINT "@@@@@"
110 LPRINT CHR$(27)"%"CHR$(0);
120 LPRINT "@@@@@"
130

In line
10,
the ESCape “x” command selects draft style printing.
The actual character definition starts in line 20. The two at signs
(@) in line 30 represent nl and n2, the range of characters being
defined (in this case, a range of one). Line 40 contains
d0, dl,
and
d2.
The information about the actual character design (which is con-
tained in the data statements at the end of the program) is sent to the
printer in the loop between lines
50
and
70.
Note
When defining Letter Quality or proportional characters, put
a WIDTH statement in your program to prevent carriage
return and line feed codes from interfering with your defini-
tions .
Printing User-Defined Characters
If you entered the example program above, you defined an arrow
and placed it in the RAM location for ASCII code
64
(replacing the at
sign). You can now print out a three line sample of your work. The
