User-Defined Characters
An example character definition program should make this clear:

In line 10, the ESC 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
do,
dl,
and
d2.
The information about the actual character design (which is
contained in the data statements at the end of the program) is sent
to the printer in the loop between lines 50 and 70.
When defining Letter Quality or proportional characters in
BASIC, put a WIDTH statement in your program to prevent
carriage return and line feed codes from interfering with your
definitions.
