Assign the random number a variable, split the number, then run checks against the new re-roll. Post some example code that you have already started working on.

Something like this ?

#include <Array.au3>

Global $_Array[1]

While 1
   $_Var = Random ( 1, 20, 1 )
   If Not _AlreadyInArray ( $_Array, $_Var ) Then _ArrayAdd ( $_Array, $_Var )
   If UBound ( $_Array ) -1 = 4 Then ExitLoop
WEnd

_ArrayDisplay ( $_Array )

Func _AlreadyInArray ( $_SearchArray, $_Item )
    $_Index = _ArraySearch ( $_SearchArray, $_Item )
    If @error Then
        Return False
    Else
        If  $_Index <> 0 Then
            Return True
        Else
            Return False
        EndIf
    EndIf
EndFunc ;==> _AlreadyInArray ( )

Why _ArraySearch()?

#Include <Array.au3>

Dim $Val[4]

For $i = 0 To UBound($Val) - 1
    While 1
        $Val[$i] = Random(0, 100, 1)
        For $j = 0 To $i - 1
            If $Val[$i] = $Val[$j] Then
                ContinueLoop 2
            EndIf
        Next
        ContinueLoop 2
    WEnd
Next

_ArrayDisplay($Val)

Why _ArraySearch()?
