KEYBOARD CODE TABLE
This is a table of common keyboard code values that are returned to a
program when it requests keyboard input data. If this is a BIOS call, the
values are returned to the program in register AL unless the value of AL is
zero. The values with 0: are extended code values with data in AH. If this is a
DOS call and you receive a zero value, you must make another DOS call to get
the extended code value.
