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.
