User-defined Characters
A value of 136 is suitable for all characters that use the top eight
pins, start in column 1, and finish in column 9. For a character of
the same width, but printed with the bottom eight pins, al should
be 8. For any other character, follow
1. If you design a character narrower than nine columns, you can
balance the number of empty columns on either side with the
following method: starting with al equal to 8, subtract 1 for
every blank column on the right and add 16 for every blank
column on the left.
2. . If the character uses the top eight pins, add 128.
For example, if
3, and ends in column 7, the calculation is as follows:
start with al = 8
l
subtract 2 for two blank columns on the left, giving al = 6
l
add 32 for two blank columns on the left, giving al = 38
l
add 128 to print with the top eight pins, so that al = 166.

Printing
If you entered the example program on page 4-25 you defined a
heart and placed it in the RAIvI 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 170
the program) print the normal at sign; the second line (line 190)
prints the heart that you defined.
Run the program to see the printout below.
