Ron, > Can anyone explain why should NIL not be a valid value?
All values saved to XML by using TXmlDocument class have to be strings, or it'll GPF. So, as every value have to be converted into a string, a Nil value becomes the same than an empty string (or any special string, like "Nil"). In the previous case, I was wrong, and neither .F. not 0 could be saved to XML. But a string with only spaces or tabs does, and it was not working before. IMO, a reasonable way to make the class to work in all cases is to convert all values to strings internally, avoiding GPFs or RTEs. The same way that many of us did with .ini files or windows' registry. Later, when a program reads the data, it has to reconvert the values to the needed type, but it's its problem ;-) Regards, Jose F.
