ITEM index thing

If thing is a word, ITEM outputs the index-th character of the word.

If thing is a list, ITEM outputs the index-th member of the list.

If thing is an array whose origin is 1 (which is most arrays), ITEM outputs the index-th element. If thing is an array whose origin is not 1, then ITEM outputs the element that is at index - origin + 1.

An index starts at 1 for words and lists; the starting index of an array is specified when the array is created.
