Do you know where your variables are?

I believe what you want is:
my %hash = @{ $diary_data[0] };
The "Reference found where even-sized list expected" stems from you trying to assign a scalar reference to a hash, but a hash expects a list with an even number of elements. You can reproduce that error from the command line:
perl -w -e "$a[0]=[1,2];%hash=$a[0]"
The following eliminates the error:
perl -w -e "$a[0]=[1];%hash=@{$a[0]}"


Join the Perlmonks Setiathome Group or just click on the the link and check out our stats.

Update: Fixed error in original reply. I had %{ $diary_data[0] } instead of @{ $diary_data[0] }.

Update 2: Just saw AgentM's update. He was actually right. This code:

my %hash = %{ $diary_data[0] };
Will force a "Can't coerce array into hash" error.

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.
