    Why are arrays usually processed with for loop?

    Arrays comes from their facility of using an index variable to traverse the array, accessing each element with the same expression a[i]. All the is needed to make this work is a iterated statement in which the variable i serves as a counter, incrementing from 0 to a.length -1. That is exactly what a loop does.

    Because it's the simplest most logical way to do it. You can go through an array other ways but this is the most common.

    ARRAY statements are common tools in the DATA step. Together they allow us to iteratively process large amounts of data with a minimum amount of code.
