Appendix B
ASCII Character Codes
Appendix B shows the American Standard Code for Information Interchange (ASCII) on the
following pages. The characters in the CHAR column appear on your display when you type
the corresponding ASCII code (as described in Chapter 6, The Keyboard). The characters
that are printed, however, depend on the software you are using. For most software, the
printed output for decimal codes 32 to 128 will match your screen display.
