KEYBOARD ASCII AND SCAN CODES
The table in this appendix lists the keys on the Tandy 1000 key-
board in scan code order, along with the ASCII codes they gener-
ate. For each key, the following entries are given:
Scan Code — A value in the range 01H-5AH which uniquely
identifies the physical key on the keyboard that is pressed.
Keyboard Legend — The physical marking(s) on the key. If
there is more than one marking, the upper one is listed first.
ASCII Code — The ASCII codes associated with the key. The
four modes are:
Normal — The normal ASCII value (returned when only the
indicated key is depressed).
SHIFT — The shifted ASCII value (returned when SHIFT is
also depressed).
CTRL — The control ASCII value (returned when CTRL is
also depressed).
ALT — The alternate ASCII value (returned when ALT is
also depressed).
Remarks — Any remarks or special functions.
The following special symbols appear in the table:
x Values preceded by "x" are extended ASCII codes (codes
preceded by an ASCII NUL, 00).
— No ASCII code is generated.
* No ASCII code is generated, but the special function
described in the Remarks column is performed. If no
comment is included, the key does not generate a code
and no function is performed.
Note: All numeric values in the table are expressed in
hexadecimal.
