10-1. Creating and Accessing a VARRAY
Problem
You have a small, static list of elements that you initialize once and that would benefit from using in a loop body.

Next, declare the variable that will hold the data using the newly defined type. For example, the following code creates a varying array to hold the abbreviations for the days of the week:
DECLARE
TYPE dow_type IS VARRAY(7) OF VARCHAR2(3);
