That's not Peter's intention, Phil. If I understand correctly, he wants to
construct a loop, where \n contains the loop's counter (and the integer
representation of the character to be replaced, if I understand correctly),
so he does not want to define \n, but define whatever \n contains. I am
still too confused by \expandafter's and \csname's to implement that
myself...
Hope that helps,
Susan
