This covers e.g. characters like '$' which do not have any standard meaning in C++ (i.e. they are not part of any token). But IIRC, two single quotation marks ('') without any characters in between also fall into this category, because this cannot be a valid character-literal. So each quotation mark is a "non-whitespace character that cannot be one of the above". Regards, Christoph --- [ comp.std.c++ is moderated.
