I see no X here.
     
         Hackers (and the interactive computer games they
        write) traditionally favour this slightly marked usage over
        other possible equivalents such as "There's no X here!" or "X
        is missing."  or "Where's the X?".  This goes back to the
        original PDP-10 {ADVENT}, which would respond in this wise if
        you asked it to do something involving an object not present
        at your location in the game.
