If you break down what you've written into an English approximation, you get something like this:
##################### Create a variable $text, then assign $text the value 'hello'; Create a variable $text2, then assign $text2 the value 'bye'; Create a variable $text3, then substitute all instances of 'hello' inside of $text3 with 'bye'; Print the contents of $text3 ##################### You are getting a warning because Perl is wondering why you want to print an empty variable. I'm wondering what you were expecting to happen. It sounds like you haven't gotten the hang of the s/// operator. You might want to reread the section of 'perldoc perlop' about "quotes and quote-like operators". -----Original Message----- From: Dave Adams [mailto:[EMAIL PROTECTED] Sent: Thursday, October 13, 2005 11:51 AM To: beginners perl Subject: Simple Substition Question My Code: ------------------ #!/usr/bin/perl -w use strict; my $text= 'hello'; my $text2 = 'bye'; my $text3 =~ s/$text/$text2/g; print $text3; My Error: --------------- F:\perlex\findpara.pl line 5.
