Help with Jumping Sprite

-----------------------------------

So im trying to make a platformer game so that by pressing the up arrow key my sprite jumps and then falls due to gravity but when i hold the up arrow ke down i want the sprite to jump higher and possibly fall slower. So far i have the first part with the jumping and the falling but i dont know how to detect if the up arrow key is held down, so my question is how do you detect when a key is held down. here is some of the code i am using: 

if keys (KEY_UP_ARROW) 
        yPosition += 50
    end if

    if yPosition  > 0 then
        yPosition -= 1
    end if

P.S. sorry if my format or how ive written this is bad, im new to this site and the link to the site rules page wasn't working.
