Creates an array object with the array elements indicated by the expression parameters. The array elements are numbered with a base index of 1.

Average array elements: AVERAGE(<ARRAY>)
Returns the average value of elements in the array.

Element by Element Array Comparison:  EQUAL(<ARRAY>, <ARRAY>)

Array element count: LEN(<ARRAY>)
Returns the number of elements in the array.

Largest array element: MAX(<ARRAY>)
Returns the largest element in the array. Items in the array are compared numerically or alphabetically.
