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.
