The latest version of the complete perlfaq is at http://faq.perl.org . -------------------------------------------------------------------- 4.61: How can I always keep my hash sorted? You can look into using the "DB_File" module and "tie()" using the $DB_BTREE hash bindings as documented in "In Memory Databases" in DB_File. The "Tie::IxHash" module from CPAN might also be instructive. Although this does keep your hash sorted, you might not like the slow down you suffer from the tie interface. Are you sure you need to do this? :) -------------------------------------------------------------------- The perlfaq-workers, a group of volunteers, maintain the perlfaq.
