You imply, but don't say explicitly, that all your arrays are the same size. Is this correct? Assuming it is, you have something like:

@numbers = (1,2,3,4,5,6,7); @words = ('one', 'two', 'three', 'four', 'five', 'six', 'seven'); @odd_even = ('odd', 'even', 'odd', 'even', 'odd', 'even', 'odd'); @prime = ('not', 'prime', 'prime', 'not', 'prime', 'not', 'prime');
And you want to be able to sort all of them together, based on one of them -- bringing the even numbers to the front, say?

Have you considered an array of arrays?

@numbers_with_attributes = ( [1, 'one', 'odd', 'not'], [2, 'two', 'even', 'prime'], [3, 'three', 'odd', 'prime'], [4, 'four', 'even', 'not'], [5, 'five', 'odd', 'prime'], [6, 'six', 'even', 'not'], [7, 'seven', 'odd', 'prime'], ); @alpha_sort = sort { $a[1] cmp $b[1] } @numbers_with_attributes;

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