      unset %times
      unset %timestotal
      unset %number
      unset %upper
      unset %numalp
      unset %char

can be shortened into

unset %times %timestotal %number %upper %numalp %char

or instead of using /set you can use /var to make it local and they will automatically be unset after script is done processing
