Hi Perlmonks!, you just helped me out very fine in an old post, but now there is a change which leads me to a new question. I found out that replacing of a single word or word combinations sometimes does not work although I mark them for not beeing interpreted. In this case I have a txt document which includes '+#' . Perl is not able to replace this two signs by '$coin22'. With other signs it just works fine. How can I improve my program to not interpret the strings he wants to read in at all? Here my skript: 

#!/usr/bin/perl -w
#use strict;
my $SCU = 'C:/Users/user/Desktop/a.txt';
open (FILE, '<', $SCU) or die "$SCU File not found : $!";
my @lines = <FILE>;
close (FILE);

my $A= '+#';
my $B= '$coin22';

my @newlines;

   push @newlines, s/$A/$B/rg for @lines;

open (FILE, '>', $SCU) or die "Could not open file $SCU: $!";
print FILE @newlines;
close (FILE);

Thank you very much in advance! Best regards
