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
I
and, 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.
