Unique Random Number Generator

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".
