  @TokOut You can't make people read or comment on your discussions. As for string.random(), there isn't anything like that, but you can write your own function that does it.

  @TokOut Here's a function that will return 2 strings of random letters. One is upper case and the other is lower case. Just change the value sent to stringRandom for different string lengths.

  function setup()
      print(stringRandom(8))
  end
  
  function stringRandom(x)
      local valU,valL="",""
      for _=1,x do
          valU=valU..string.char(math.random(string.byte("A"),string.byte("Z")))
          valL=valL..string.char(math.random(string.byte("a"),string.byte("z")))
      end
      return valU,valL
  end

  @TokOut Here one that will give you 8 random letters from the letters you send to the function.

  function setup()
      print(stringLetter("qwertyuiop",8))    
  end
  
  
  function stringLetter(s,w)
      local str=""
      for _=1,w do
          v=math.random(1,s:len())
          str=str..string.sub(s,v,v)   
      end
      return str 
  end

  @dave1707, can you do with this something like

  for x = string.byte("a"), string.byte("z") do
  .....
  

  And any way for this random strings, to use for a-z and the "_" symbol?

  @TokOut You could use this. You could also add numbers or anything else you want to the list..

  function setup()
      print(stringLetter("abcdefghijklmnopqrstuvwxyz_",8))    
  end
  
  function stringLetter(s,w)
      local str=""
      for _=1,w do
          v=math.random(1,s:len())
          str=str..string.sub(s,v,v)   
      end
      return str 
  end
