Rnd
Gives a random number
Rnd[(number)]
The Rnd function returns a value less than 1 but greater than or
equal to 0.
The value of number determines how Rnd generates a random
number:
If number is 
Rnd generates 
Less than zero 
The same number every
time, using number as the
seed. 
Greater than zero 
The next random number in
the sequence. 
Equal to zero 
The most recently
generated number. 
Not supplied 
The next random number in
the sequence. 
For any given initial seed, the same number sequence is generated because
each successive call to the Rnd function uses the previous number as
a seed for the next number in the sequence.
Before calling Rnd, use the Randomize statement without an
argument to initialize the randomnumber generator with a seed based on the
system timer.
To produce random integers in a given range, use this formula:
Int((upperbound  lowerbound + 1) * Rnd + lowerbound)
Here, upperbound is the highest number in the range, and
lowerbound is the lowest number in the range.

Note To repeat sequences of
random numbers, call Rnd with a negative argument immediately
before using Randomize with a numeric argument. Using
Randomize with the same value for number does not repeat
the previous sequence.
