Randomize PowerScript function
Description
Initializes the random number generator so that the Rand function
begins a new series of pseudorandom numbers.

Description |
|---|---|
|
n |
The starting value (seed) for the random |
Return Values
Integer. If n is null, Randomize returns null.
The return value is never used.
Usage
The sequence of numbers generated by repeated calls to the Rand function
is a computer-generated pseudorandom sequence. You can use the Randomize function
to initialize the random number generator with a value from the system
clock, or some other changing value, so that the sequence is always different.
For testing purposes, you can select a specific seed value, which
you can reuse to make the pseudorandom sequence repeatable each
time you run the application.
Include Randomize in the script for the
Open event in the application.
Examples
This statement sets the seed for the random number
generator to 0 so that calls to Rand generate
a new sequence each time the script is run:
|
1 |
<span>Randomize</span>(0) |
This statement sets the seed for the random number
generator to 4 so that calls to Rand repeat a
specific sequence each time the random number generator is initialized:
|
1 |
<span>Randomize</span>(4) |
