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 these rules to calculate al:

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 a character uses the top eight pins, starts in column 3, and ends in column 7, the calculation is as follows:

•start with al = 8•subtract 2 for two blank columns on the left, giving al = 6•add 32 for two blank columns on the left, giving al = 38•add 128 to print with the top eight pins, so that al = 166.

Printing userdefined characters

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 and 210 of the program) print the normal at sign; the second line (line 190) prints the heart that you defined.
