Random Number Generator

To generate 10 unique, non-doubling random numbers this works:

Set Variable: "i" = 1
Loop While (i <> 11)
Set Variable: "rnd" = Random (10)
Set Variable: "x" = 1
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
If (rnd ne "")
Set Variable: "Temp" = Temp & rnd
Set Variable: "i" = i + 1
End If
End Loop
