For the purposes of PROMOTIC system, it is more usefull to use the method: Pm.Random.
n = Rnd[(number)]
|number||(Integer) Any valid numeric expression. The value of number determines how it generates a random number.|
less than 0 - the same number every time, using number as the seed
greater than 0 - the next random number in the sequence
equal to 0 - the most recently generated number
if 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 random-number 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)
where upperbound is the highest number in the range, and lowerbound is the lowest number in the range.
To repeat sequences of random numbers, then 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.
