It's rather useless to put a value in a variable when you immediately replace it with another.

Then you're not dealing with a single value as you claimed. You want to iterate over a list of values. Why do you think it's a problem storing that list in an array?

As for how, you've already been shown how. You were even given a fully functional program.

Thanks for all your efforts. Let's simplify this. I am trying to put this in a subroutine. But it is not working. can you suggest on this?

      sub OfficePhoneNumber

      {

      my @numbers = @_;

      my $number;

      my @results;

      foreach $number (@numbers)

      {

      if ($number =~ m/(^\d{3}-\d{4}$)/)

      {

      push @results, $number;

      }

      }

      return @results;

      }
