Title:

For the record:: James Hester wrote: Do we all agree with the following assertion regarding full point and question mark? (1) A full point/question mark inside string delimiters is *not* equivalent to an undelimited full point/question mark I agree with this statement. Numbers: I believe that strings that could be interpreted as numbers are nevertheless (in a formal sense) just strings in the context of the post-parse abstract data model.  Therefore, whether or not a numerical string is delimited does not change its value: 4.5 and "4.5" are identical values. I have not particular views on this as I am not involved in writing software. David
