In line 10, the ESC x0 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
contained 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 in BASIC, put a WIDTH statement in your
program to prevent carriage return and line feed codes from
interfering with your definitions.
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 first and third lines (printed by lines
80 and 120 of the program) print the normal at sign; the second
line (line 100) prints the arrow that you defined.
