You may try doing something like this:
use strict; my @the_data = ( { field1 => 'first item', field2 => 8, field3 => 'z', }, { field1 => 'second item', field2 => 2, field3 => 'b', }, { field1 => 'third item', field2 => 6, field3 => 'c', }, ); # sort @the_data by field2 and field3... for ( sort { ($$a{field2} <=> $$b{field2}) && ($$a{field3} cmp $$b{fie +ld3}) } @the_data ) { print $$_{field1} . "\n"; }
The output that I get is:
second item third item first item
In your case, you may have maturity_yrs in place of field2 and rich_cheap instead of field3 inside my sort statement. You can sort your structures in any imaginable way using the sort and your own custom built sort subroutines.
