Expects: AX    0003H

Returns: BX    Button status: bit 0 = left button down   (BX & 1) == 1

bit 1 = right button down  (BX & 2) == 2

bit 2 = center button down (BX & 4) == 4

CX    X coordinate (horizontal)    divide by 8 for text clm

DX    Y coordinate (vertical)      divide by 8 for text line

Info: This returns the current position of the mouse pointer, and the

current status of the mouse buttons.

Rather than constantly polling this function, many programmers

prefer to install a mouse event handler via INT 33H 000cH or

INT 33H 0018H and maintain global variables for instant access to

mouse information.

Notes: All X,Y coordinates are virtual coordinates and when working with

text mode, you must divide each value by 8 to get a character

clm,row.
