It sounds like you are looking for the e option on the regex, but a regex is really not the right answer to your problem. Take a look at split instead: #!/usr/bin/perl use warnings; use strict; use List::Util qw/sum/; my $number = 123; $number =~ s/([0-9])([0-9])([0-9])/$1+$2+$3/ge; print "$number\n"; my $other = 12345; $other = sum(split //, $other); print "$other\n"; -- Chas.
