Use a hash instead:

#!/usr/bin/perl use warnings; use strict; my %booksByBorrower = ( adam => {"Learning Perl" => {borrowed => '2015-12-17'}}, jake => {"Programming Perl" => {borrowed => '2015-12-08'}}, john => {"Programming Perl" => {borrowed => '2015-12-12'}}, betty => {"High Order Perl" => {borrowed => '2015-12-10'}}, ); for my $name (sort keys %booksByBorrower) { print "$name\n"; for my $book (sort keys %{$booksByBorrower{$name}}) { print " Borrowed $book $booksByBorrower{$name}{$book}{borrowe +d}\n"; } }


adam Borrowed Learning Perl 2015-12-17 betty Borrowed High Order Perl 2015-12-10 jake Borrowed Programming Perl 2015-12-08 john Borrowed Programming Perl 2015-12-12

Of course for this sort of task you should really be using a database, but that's a little heavy for such a trivial example.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
