This routine takes a string stored in Str1 and scramble it. The results is contained in Ans. For example, "ABCDE12345" could be scrambled to "B34AC1DE25".

:cumSum(1 or Ans→L₂

With your string stored in Str1, it creates L₁={1,2,3,4,…,length(Str1)}. After that, L₂ is created randomly to sort L₁ in function of L₂. L₁ now could look like {5,3,4,1,2} if you entered a 5 character string. In the For( loop, it takes one by one the character of Str1 accordingly to L₁ to store it to Ans. Your scrambled string is now in Ans.
