The GEMDOS function Cconin(), and the
BIOS function Bconin() (when used to read the console de
vice keyboard), both return a two-byte keycode, which is ex
tended into a longword. The first byte of the keycode, which
is found in the second byte of the longword, is usually a
unique key identifier that refers to the physical key that was
struck, regardless of shift-key combinations. The second
byte, which is found in the last byte of the longword, is usu
ally the ASCII value of the key combination, which does de
pend on the state of the shift keys (Shift, Control, and Alter
nate). The following table shows the keycodes, as four-digit
hexadecimal numbers, for all key and shift combinations.
