Appendix BASCII CHARACTER SET
B. Appendix B ASCII CHARACTER SET

B.1 INTRODUCTION

This appendix lists, in Table B-1, the 256-character ASCII code set including the decimal and
hexadecimal values. All ASCII symbols may be called while in DOS or using standard text-mode
editors by using the combination keystroke of holding the Alt key and using the Numeric Keypad
to enter the decimal value of the symbol. The extended ASCII characters (decimals 128-255) can
only be called using the Alt + Numeric Keypad keys.
NOTE: Regarding keystrokes, refer to notes at the end of the table. Applications may interpret
multiple keystroke accesses differently or ignore them completely.
