In perl (using cgi), what is the code for a return?
I know it should be '\n', but when I take what's in a textarea box, and use $variable =~ s/\n//eg; it doesn't remove all of the returns. Is something wrong with that little bit of code? What I want to do Iis remove all of the carriage returns, so that if the user simply puts carriage returns in the textarea box, the variable will hold nothing, so that I could use if ($variable eq "") { $variable = "Some Default Message"; } If someone helps me, I'd appreciate it!
