Whenever the [GOLD] key is pressed, 13 bytes define the key number of the

logical keyboard.  These bytes are referred to as a keyboard macro.  The first

byte specifies the length of the macro.  The second through 13th bytes provide a

combination of scan codes, break codes, or extended key codes.  A keyboard

macro may consist of only one byte of code information.
Keyboard macros are invoked whenever you press the [GOLD] key and then

immediately press a second key.  You can cancel a keyboard macro by (1)

pressing the gold key again before pressing any other key or (2) by releasing the

key that you pressed after you pressed the [GOLD] key.  Keyboard macros may

continue to repeat as long as the second key is pressed and held.
Macros comprising only one byte of code information are treated as special keys.

There are five predefined specialĆkey macros processed internally to the H8:

"

Contrast up

"

Contrast down

"

Backlight on/off toggle

"

Increase backlight intensity

"

Decrease backlight intensity

The standard macros for the key numbers of the physical keyboard are defined

as follows.  Key numbers not listed are undefined.

The interface for keyboard macro redefinition is a call to INT 15h with the

following parameters:
On Entry:

ES:DX = Points to the 12Ćbyte macro definition

CL = Contains the length of the macro

BL = Contains the logical key position

BH = 14h (Define key macro function number)

AX = 5380h (OEM function call)

On Return:

AH = Nonzero if error
