thanks for the info brian_d_foy. however after taking your advice and making my scalar a lexical i am still unable to re-use my hash each time loop through my foreach $uniqu ... statement. i also took the advice given by isotope and Scarborough and made my counter look like $hash{$rule}++ and also tried to use the  undef %hash; at the end of my loop, but still with no luck. here is what my loop looks like now:

foreach $uniqu (@uniqu){
  my %hash;
  ...(process each key/value)...
  undef %hash;
}

it still seems as though every time i go through my foreach loop, the clearing of my %hash is not taking place. any other suggestions?

• 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).
