Appendix c
DO W/i/LOAD
CHARACTER GENERATOR
With this printer you can create new characters and symbols, download
their dot data, and have them printed in place of selected characters in the
regular character set. Characters that can be generated in this way range
from simple but useful symbols like the check mark through complex Chinese
or Japanese characters.
The process of designing new characters with paper and pencil is
somewhat time-consuming. The program listed in this appendix enables you
to do everything on the computer screen. It also enables you to maintain
disk files of character data for downloading when required.
The creation of a car-shaped symbol as a draft character ( oh ) and
near-letter-quality character ( o) ) is explained below.
