12.2 Controlling Array Traversal and Array Sorting
gawk lets you control the order in which a ‘for (indx in array)’ loop traverses an array.
In addition, two built-in functions, asort() and asorti(), let you sort arrays based on the array values and indices, respectively. These two functions also provide control over the sorting criteria used to order the elements during sorting.
