You are precisely correct! The function as I wrote should also eliminate case differences as well.

>>>Does anyone know of an existing function, routine, or 3rd-pary product that will show the differences between one character string and another? I'm not totally sure exactly how this would work, but one example follows:
>>>Original string = "The cat jumped over the fence."
>>>New string = "The cat jumped over the fence to cross the road."
>>>Routine would return something like: "to cross the road."
