RE: Hash Questions
Hello, I have defined a hash in a specific order. When I print the hash elements, the hash become unsorted and prints the elements out of my original order. Is there any way to restrict the hash from internally sorting the elements? snip 1) you can not determine the order of elements in a hash table. 2) Perl does not sort its hash tables. 3) Carl's solution to this issue is exactly what I use to pull out data from a hash in a particular order.

Then again, just because Perl doesn't maintain hash key order by default doesn't mean we can't. Everybody knows nothing is impossible in Perl. Check out Tie::IxHash if you haven't found it already. jpt ___ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/listinfo/perl-win32-users

Should be 'qw'.

My bad. Another typo. Should be qw not wq.
