The Variable "x" is used to check the content of Variable "Temp" which will hold the final result.
`Set Variable: "x" = 1`
And now for the tougher bit:
```Loop While (x <> (Length(Temp)+1))
If ((Substring (Temp, x, 1))  eq rnd)
Set Variable: "rnd" = ""
End If
Set Variable: "x" = x+1
End Loop
```
This checks whether a generated random number, held in Variable "rnd", already exists in the "Temp" variable. This is done by looping through every digit in "Temp". The number of loops is determined by the Length function. If the number does exist the variable "rnd" is cleared. If the generated number is not present in "Temp" it is added to it.
```If (rnd ne "")
Set Variable: "Temp" = Temp & rnd
Set Variable: "i" = i + 1
End If
```
We continue the Loop by increasing "i".

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
