I wonder if anybody here knows what a 'TI-85 Graphics Calculator
Guidebook' is? They're standard with each TI sold.. And they're not just
in there for packaging material. From page 3-6 in the book:


"rand (random number) generates and returns a random number greater than
0 and less than 1. To control a random number sequence, first store an
integer seed value in rand; for example 0->rand. If you store 0 to rand,
the TI-85 uses the factory-set seed value. When you reset the TI-85,
rand is set to the factory seed.


"For example, 0->rand:rand*3 always returns 2.83079220478."


So storing an integer into rand will affect what comes out..
