will just echo from 1 - 255 (english chars) -- was meant for something long ago, forgot it. :)

alias fib {
  var %i = 3
  var %x = 0
  var %y = 1
  echo -a 1.) 0
  echo -a 2.) 1
  while (%i < 256) {
    var %z = $calc(%x + %y)
    echo -a %i $+ .) %z
    var %x = %y
    var %y = %z
    .inc %i
  }
}
