Hi Glenn,
I spent a little time examining the StrDiff() function
that you submitted because I believe it can be useful.
Here is what I found:
* It will show the difference between two strings ONLY if the
* shorter of the two strings has an EXACT MATCH within the
* the longer of the two strings. The first string
* "The cat jumped over the fence" has an exact match in the
* second string, but "The cat jumped over the fence." (which
* has a period) does not match.
*
* Looks like most of this function should be in a "DO WHILE"
* loop where the shorter string is incrementally compared to the
* longer string until it no longer matches like this:
*
* "The"
* "The cat"
* "The cat jumped"
* .
* .
* .

Thanks for the interesting function.
Terry

>>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."
>>Etc...
