I may be wrong... (Score:1)

I read in some blog discussion or newsgroup that 'cls' is not really a callable command in Windows, it is a hack. Which is why it doesn't work.

I will try and remember the conversation...

  Or maybe I don't understand his problem...
  
  If I run:
  
  $clear = "cls";
  system($clear);
  
  That clears my screen. So maybe I don't know his problem.

    I think this is it. 'cls' is not a program like cls.exe or cls.com but it is a command available to the CMD environment shell. Therefore, you cannot run it with `cls` because Windows doesn't know what to do with that.
    
    You have to do something like: `cmd /c cls`
