I still am not convinced that all of the hoopla about \z is really necessary. I guess the question I need answered before I go back and change anything is this: How is the user supposed to enter an extra \n without exiting the prompt? What I mean is, the only situation in which this could make a difference is if you concede that a user can somehow enter a \n character into a prompt without returning that value back to your script. Otherwise it's your fault if you don't chomp their response.
There's a distinct possibility that I'm wrong here, but I haven't heard any really good arguments on this. -----Original Message----- From: Jeff 'japhy' Pinyan [mailto:[EMAIL PROTECTED]] Sent: Monday, March 04, 2002 1:07 PM To: Dennis G.
