I have been searching about for how to declare a variable, ranging from SuperSearch to just using the search function, and have not found an article or node that may satisfy my curiosity.

What I wish to know was that I came across another post on this node of Seekers of Perl Wisdom that looked like this:

#!/usr/bin/perl -w
use strict;
use warnings;

CheckAllPairs();
CheckAllPairs();

sub CheckAllPairs{
        my $abs_time_res=50;
        my $max_peak_time=2050;
        my $subj_num;
        my $region;
        my $region1;
        my $region2;
        my $time;
        my $peaks;
        my @act_list1;
        my @act_list2;
        my $i;
        my $j;
        my $key;
        my $delta;
        my %map;
        my $start_A;
        my $end_A;
        my $start_B;
        my $end_B;

        my @region_list = (1..38);
        my @main_subjects_list = (1..38);

I was wondering if this is a good example of declaring variables at the beginning of a script, which, in this case, also uses the recommended USE STRICT call at the beginning of this example snippet?

As always, thank you, and I think when all is said and done, I may be creating a FOR BEGINNERS section if I'm not careful.
