Regular Expressions and Private Arrays

Okay! Thanks for the help with the previous code!

I'm stuck again on something else now though. ^_^;

I have to add the values of an array @save that has numbers in it.
Code:
#! usr/bin/perl
use strict;

my $rules ="/Users/caitlin/scripts/challenge2.txt";
open my $FH, '<', $rules or die $!;
my @numbers;
my @save;


while (my $line = <$FH>){
        @numbers = split(m/[^0-9]+/, $line);
        push (@save, @numbers);

}

print @save;

It's not done yet because I have to add all the intergers in the array. The challenge2.txt contains text and numbers that I had to split. The result has empty spaces in it.

I need to take each result from the loop and add the next result to it. And as stated before, I'm dense... Smilie My attempts at it haven't amounted to executable code.

Help would be very much appreciated!
Thank you! Smilie

Perl::PrereqScanner::Scanner::Perl5(3pm)		User Contributed Perl Documentation		  Perl::PrereqScanner::Scanner::Perl5(3pm)

NAME
Perl::PrereqScanner::Scanner::Perl5 - scan for core Perl 5 language indicators of required modules VERSION
version 1.012 DESCRIPTION
This scanner will look for the following indicators: o plain lines beginning with "use" or "require" in your perl modules and scripts, including minimum perl version o regular inheritance declared with the "base" and "parent" pragmata Since Perl does not allow you to supply a version requirement with a "require" statement, the scanner will check the statement after the "require Module" to see if it is "Module->VERSION( minimum_version );". In order to provide a minimum version, that method call must meet the following requirements: o it must be the very next statement after "require Module". Nothing can separate them but whitespace and comments (and one semicolon). o "Module" must be a bareword, and match the "require" exactly. o "minimum_version" must be a literal number, v-string, or single-quoted string. Double quotes are not allowed. AUTHORS
