It's a little hard to know exactly what you're talking about since you didn't include any code. But my guess is you need to learn about references. With references you can create an array in one function and pass it to another without paying the penalty to recreate it. This is known as "pass-by-reference" to comp-sci geeks. Here's an example:

sub foo {
  my @array = ( 0 .. 100 ); # create a new array
  bar(\@array);             # pass it to bar() by reference
}

sub bar {
  my $array_ref = shift;    # get reference to foo()'s array
  foreach (@$array_ref) {   # print out each value
     print;
  }
}

If this is your first encounter with references then you've got some learning to do. I suggest you pick up a copy of Learning Perl or Programming Perl and dig in!

• 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.
