    Here is the code I updated. Please check it. Thanks.
    use warnings; use strict; my $test; my @words; open(INFO,"<","testing.pl")||die"Can't open file:$!\n"; chomp (@words=<INFO>); close(INFO); foreach @words){ if(/^\$ NAME : corry/ .. /\.EON/){ $test=$1; print $test; } }

      well, you're using $1 without using capture groups which moritz told you about , and which perlintro talks about ($1)

      why are you using $1, maybe you want to use $_?

        use warnings; use strict; my $test; my @words; open(INFO,"<","testing.pl")||die"Can't open file:$!\n"; chomp (@words=<INFO>); close(INFO); foreach (@words){ if(/^\$ NAME : corry/ .. /\.EON/){ $test=$_; print $test; } }
        I used $_ but nothing prints out.
