Ok, so I finally understand the N/a notation but am having trouble with this code. Seems that the () notation is pretty new as it is not in my Programming Perl, 2nd Edition and my perl 5.6.1 does not support it. But, my perl 5.8.0 does support it and is documented in its perlfunc manpage.

Here is the error that I get with the perl 5.6.1:

Invalid type in unpack: '(' at C:\Data\test\dcode2.pl line 8, <> chunk 1.

I am not too sure how to go about "converting" this code to work with perl 5.6.1.

BTW, still cannot get the code to work on perl 5.8.0 without an error with the "/" as stated earlier.

Ed

• 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).
