The POSIX phraseology is that "null" means the empty string.
---- POSIX phraseology applies to the POSIX language. In 'C' char *s = NULL is not the same as char *s=""; They aren't the same at the machine level nor at the language level. In perl: my $s = undef; is not the same as my $s = ""; Off hand, I don't know of any computer language that equates them (doesn't mean there is none). undef = unset null may be set but ANSI defines '\0' as NUL. Is that the same as null?
