in reply to Non-Repetitive Random Numbers

Please take a look at perl function srand.
This function "seed" the rand function so that rand can produce a different sequence each time you run your program.

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.

    Please take another look at the documentation you linked to.

    The docs for rand state that it "Automatically calls srand unless srand has already been called." It is not necessary to call srand manually and doing so may actually reduce the randomness of the sequence your receive. (If you call srand repeatedly, it will almost certainly do so.)
