Understanding VarraysThe Items of type VARRAY are termed as the varrays. They permit you to relate a single identifier with the whole collection. This relationship lets you manipulate the collection as an entire and reference individual elements easily.

For e.g. the current upper bound for varray Grades is 7, but you can expand it to 8, 9, or 10. And hence, a varray can contain a varying number of elements, from zero (when empty) to the highest specified in its type definition.
