Array is a constant already defined (== [].class). I wonder
why you get no warning message. Say

  char_array = ("a".."z").to_a

Using globals is not recommended. Although, try something
like

  def join_them
    $JOB ||= ""
    $Text = $Oldtext3 + $OldText2 + $OldText + $JOB
  end

Probably you meant $Text, not $JOB.
