Parameter

Parameter	Description
delim	what delimiter to use in between array elements.
maxValues	how many array elements to include. When less than 0, all values are included.

If any elements are not included, <code>...</code> will be inserted after the last element.
useBrackets	add [] to outside of string iff true
