VBScript Randomize Statement

Initializes the random-number generator.

Syntax: VBScript Randomize Statement

Randomize [number]

Arguments: VBScript Randomize Statement

number

Any valid numeric expression.

Remarks: VBScript Randomize Statement

Randomize uses number to initialize the Rnd function random-number generator, giving it a new seed value. If you omit number, the value returned by the system timer is used as the new seed value.

If Randomize is not used, the Rnd function (with no arguments) uses the same number as a seed the first time it is called, and thereafter uses the last generated number as a seed value.

The following example illustrates use of the Randomize statement.

Dim MyValue, Response

Randomize ' Initialize random-number generator.

Do Until Response = vbNo

MyValue = Int((6 * Rnd) + 1) ' Generate random value between 1 and 6.

MsgBox MyValue

Response = MsgBox ("Roll again? ", vbYesNo)

Loop

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.
