You shouldn't use $a as variable. $a and $b are special variables in perl, used to hold results from the sort function.

As stated by others, use the Data::Dumper module for printing hashes.

use Data::Dumper; my %not_a_or_b=(); $not_a_or_b{1}{"a"}{"A"}="FIRST"; $not_a_or_b{1}{"c"}{"B"}="THIRD"; $not_a_or_b{1}{"b"}{"C"}="SECOND"; foreach my $k1 ( sort keys %not_a_or_b ) { foreach my $k2 ( sort keys %{$not_a_or_b{$k1}} ) { foreach my $k3 ( sort keys %{$not_a_or_b{$k1}{$k2}} ) { print "$not_a_or_b{$k1}{$k2}{$k3}\n"; } } } print Dumper(\%not_aor_b);

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 or How to display code and escape characters are good places to start.
