12.3 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.
