  dice_roll := ||(? seed) // 6 + 1
  

  
  where seed is a long. If that doesn't make sense, look up the ? operator in the Spin manual.

  Thanks for your answer. This don't works correctly for my application. Because it need a reset in order to get a new result, I would like to get a new random number everytime the function is called ... :-/

  You need a re-seeding source (a photocell or...) or the die will, naturally, turn up the same result every time.

  If you need a different result after every reset, you could also try Chip's Real Random object in the OBEX:
