pack("N(N/a*)",$index{$key},$key)! meaning that the $index{$key} is written as a Number, and the $key as a length-prefixed string.

The parenthesis are for grouping. Their meaning is half-hidden in the documentation...

Regarding the error: I don't get it. I tested the code.

The unpack is right as it is: it means "a series of pairs of Numbers and length-prefixed strings (in unpack you must not put the *, see the docs)

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.
