G'day rasgolla,

Welcome to the monastery.

"I am getting output as ..."

Please show actual output between <code>...</code> tags. That way we can see exactly what you're seeing.

Please also show expected output (again, between <code>...</code> tags). Then we can see the difference between what you got and what you were trying to get.

From what you've posted, if

DEBUG( "DEBUG: - difference links values $difference[0] " );

is producing

DEBUG: - difference links values ARRAY(0x34276a0)

but you actually wanted something like

DEBUG: - difference links values val1 val2 ... valN

then you'll need to dereference the $difference[0] arrayref:

DEBUG( "DEBUG: - difference links values @{$difference[0]} " );

That possibly raises a few questions, most of which may be answered by "Perl references short introduction".

If you have further questions, please follow the guidelines in "How do I post a question effectively?". Also, using a logical indentation, will make your code more readable for both you and us: that equates to less errors by you and, for us, a greater inclination to actually read your code.

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 or How to display code and escape characters are good places to start.
