Re^2: Sorting multiple arrays

This doesn't sort @array_b. The OP could then just numeric sort @array_b in a separate operation.

Maybe I skimmed too fast, but I thought the sorting of array_b was only a logical sort to show how array_a needed to be reordered. If that's not the case, saving the indicies and using them twice would do the trick: `my @indicies = sort { $array_b[$a] <=> $array_b[$b] } 0..$#array_b; my @sorted_a = @array_a[@indicies]; my @sorted_b = @array_b[@indicies];` [download] -- Randal L.
