    Here a quick modified coding to look at the string seen in a highlighted word text (I had to chop a lot out to get it in the post size limit, the uploaded file has a fuller version)


    Code:

It seems to match  the first and Third " together as a  valid pair   but  the other  " in the middle of the  3 "s is also syntax OK, and does not error as    """     would  because  of the final 4th " which it syntaxly sees as a valid pair matched simultaneously as it does some similar check on the  first  and Third    as a concluding  string pair.  All is well except that  the second  "  is captured   within a   accepted  enclosing pair made up of the first and third  "   At the same time the 4th  "  is accepted as a final concluding   "   paired with the   second which it is  using but at the same time now isolated from.
