I'd seen, but never really taken any notice of the 'w' format for pack & unpack. Totally made for the job.

Perhaps the only downside of using 'w' instead of 'S' or 'L' is that you need to unpack the whole string to get to an individual value. With 'S' or 'L' you could have indexed into the string with substr to read or write an individual value. How much of a penalty this is will depend on your application and whether you will always need to access all the values in any given string each time.

Probably worth it if the savings on space are enough.

Examine what is said, not who speaks.

The 7th Rule of perl club is -- pearl clubs are easily damaged. Use a diamond club instead.

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.
