Tandy 1000 MS-DOS User Manual

Appendix A / ASCII and Scan Codes
means this key combination is suppressed in the keyboard
driver
X values preceded by X
are extended ASCII codes (codes pre-
ceded by
an ASCII NUL)
t The I ALI I key provides a way to generate the ASCII codes of
decimal numbers between 1 and 255. Hold down
the I ALI I
key while you type on the numeric keypad any decimal
number between 1 and 255. When you release
ALT, the
ASCII code of the number typed is generated and displayed.
Note: When
the NUM LOCK light is off, the Normal
and SHIFT columns
for these keys should be reversed.
ASCII Character Codes
The ASCII and Scan Codes table listed the ASCII codes (in
hexadecimal) generated
by each key. This table lists the charac-
ters generated by those ASCII codes.
Note: All ASCII codes
in this table are expressed in
decimal form.
You can display the characters listed by doing either of the
following:
• Using
the BASIC statement PRINT CHR$(code), where code is
the ASCII code.
• Pressing
I ALI Iand, without releasing it, typing the ASCII code
on the numeric keypad.
For Codes 0-31,
the table also lists the standard interpreta-
tions. The interpretations
are usually used for control func-
tions or communications.
Note: The
BASIC program editor has its own special
interpretation of some codes and may not display
the
character listed.
