# Randomize Statement

Initializes the random-number generator used by the Rnd function.

## الصياغة:

    Randomize [Number]

## المعاملات:

Number: Any integer value. Used as seed to initialize the random-number generator. Equal seeds result in equal random-number sequences by the Rnd function. If the parameter is omitted, the Randomize statement will be ignored.

Unless a predictable sequence of numbers is desired, there is no need to use the Randomize statement, as the random-number generator will be initialized automatically at first use – it will be seeded using a system-provided random-number generator that produces uniformly-distributed, non-deterministic random numbers. If no such generator is available on the system, the system time will be used as seed.

The Randomize statement affects BASIC's Rnd function only. Other random-number generators (for example the Calc's RAND() function, etc.) are not affected by it.

### Error codes:

5 Invalid procedure call

## مثال:

    Sub ExampleRandomize
    Dim iCount As Integer, iVar As Integer, sText As String
    Dim iSpectral(10) As Integer
        Randomize 2^14-1
        For iCount = 1 To 1000
        iVar = Int(10 * Rnd) ' Range from 0 to 9
            iSpectral(iVar) = iSpectral(iVar) +1
        Next iCount
        sText = " | "
        For iCount = 0 To 9
            sText = sText & iSpectral(iCount) & " | "
        Next iCount
        MsgBox sText,0,"Spectral Distribution"
    End Sub
