Now I know what made me think of Hollerith constants with the "H" :-) I doubt that it's "quite easy" to use Hollerith constants for humans - how often do you have to check whether you got the right number of characters when reading or writing such a constant? So the delimited form of strings is easier to handle by both humans and DFA's, a win-win situation :-) DoDi
