Do you want to avoid using the http://perldoc.perl.org/functions/reverse.html built-in function or any built-in function whatsoever? Assuming the latter you can do this: [CODE] #!/usr/bin/perl use strict; use warnings; sub my_reverse { my ($s) = @_; my $ret = ""; for my $idx (0 .. length($s) - 1) { $ret = substr($s, $idx, 1) . $ret; } return $ret; } my $string = shift(@ARGV); print "Reversed is:\n", my_reverse($string), "\n"; [/CODE] Running it gives you: [SHELL] shlomif@telaviv1:~$ perl my-reverse.pl Hello Reversed is: olleH shlomif@telaviv1:~$ perl my-reverse.pl Franklin Reversed is: nilknarF shlomif@telaviv1:~$ [/SHELL] Regards, Shlomi Fish > > Thanks, > Frank > > > On Thu, Dec 27, 2012 at 5:38 AM, Shlomi Fish <shlo...@shlomifish.org> wrote: > > > Hi chromatic, > > > > happy holidays and I hope everything is going well for you. > > > > On Fri, 2 Nov 2012 23:11:24 +0200 > > Shlomi Fish <shlo...@shlomifish.org> wrote: > > > > > Hi chromatic, > > > > > > first of all, thanks for your work on the book Modern Perl , and for > > allowing > > > free use and distribution of it. > > > > > > Now, I have mirrored a copy of it on > > > http://perl-begin.org/tutorials/modern-perl/ (latest version, as far as > > I > > > know) and there has been some interest in setting up web ads on > > > http://perl-begin.org/ .
