      In versions before 3.0.7 the meaning of
      <TT
CLASS="parameter"
><I
>max</I
></TT
> was <TT
CLASS="parameter"
><I
>range</I
></TT
>. To
      get the same results in these versions the short example should
      be <TT
CLASS="literal"
>rand (5, 11)</TT
> to get a random number
      between 5 und 15.
