Yes folks, the person who wrote the original snippet created an array of 128 values, and assigned it to scalar.

Just a minor nitpick, it was the second poster who made the scalar/array context slip. (I'm the guy who posted the first code snippet;). True to my .sig, I didn't post my code until I knew I had the correct answer. In any case, the md5sum of the correct byte streams should be...

As also noted on this page. Just for the heck of it, here's my original code. (and of course you should realize that it uses backticks to run a program called "echo" and "md5sum", hence the unix qualifier)

• 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).
