VBScript » Functions » Rnd
- Syntax:
- Rnd(Number)
The Rnd function generates a pseudo-random number greater than
or equal to 0.0 and less than 1.0.
The Number argument is optional, but different numbers
will give different pseudo-random numbers.
Note that the number generated is pseudo-random, because the same
output tends to be repeated over and over. You can use the
Randomize statement to over come this problem.

This code will generate a random number between any limits you choose. (Since the Int function always rounds down, we add one to the difference between the limits.)
