paint16b implements a mouse-driven drawing program which has the ability to exit back to DOS and also display the mouse cursor.

<syntaxhighlight lang=nasm>
org 100h ; code starts at 0x100
mov al,0x12 ; assume ah = 0 ; set graphics mode to 640*480
inc bx ; assume bx = 0 ; set to 1 (show cursor)
mloop:
int 0x10 ; first loop, switch to graphic mode
; further loops, set pixel
xchg bx,ax ; first loop, set AX to 1 (show cursor)
; further loops, restore old calling mode
xor al,0x02 ; switch modes : show cursor <-> get mouse state
; updating XY every second loop plus drawing
; one pixel left results in thicker lines
int 0x33 ; call the mouse interrupt
xchg bx,ax ; store the button state in AL for drawing
; remember the current calling mode
; for switching it later (in BX)
mov ah,0x0C ; set mode to "set pixel"
loop mloop ; dec CX -> draw one pixel left from cursor
; basically enables drawing pixels
; while the cursor is active
; allows exit if the mouse is leftmost
ret ; assume [[FFEE]] = [0] = CD20 = int 20
