If you mean, "how do you read individual presses"?... Have you looked at this Example (from DBC help):
rem ==============================================
rem DARK BASIC EXAMPLE PROGRAM 7
rem ==============================================
rem This program provides simple joystick movement
rem ----------------------------------------------
rem Set a coordinate in the middle of the screen
x=320
y=240
rem Begin main loop
do
rem Clear the screen each cycle
cls
rem Move the coordinate based on the joystick input
if joystick up()=1 then y=y-1
if joystick down()=1 then y=y+1
if joystick left()=1 then x=x-1
if joystick right()=1 then x=x+1
rem Set the ink color based on the fire button input
if joystick fire a()=1 then ink rgb(255,0,0),0
if joystick fire b()=1 then ink rgb(0,255,0),0
if joystick fire c()=1 then ink rgb(0,0,255),0
if joystick fire d()=1 then ink rgb(64,0,64),0
rem Draw a circle at the coordinate
circle x,y,20
rem End the loop
loop
I'm using a USB joypad and it works fine with these commands.
