Space spamming program?

Is there any program i can use to spam the space bar while i am holding it down? Not an autospacer which does it until you press a hotkey, something that spams the spacebar when you hold it down.

i guess it's really easy to make, ask some1 to make for u and give them ZP or something.

and why would u whant this..?

Yeah, why would you want this? Jumping makes it hard to aim with a sniper, and makes the spread on a spray double.

ORLY?
