## List Item At Index

This function is used to extract a single item from a list in a field or named variable. The item is saved to a specified variable or named variable.

The index is zero based and counts from the left. ie. 0 is the first element, 1 is the second, etc. Negative indexes count from the right. ie. -1 is the last element, -2 is the second to last element, etc. An invalid index will result in the destination variable being set to empty.

If the list delimiter resolves to be empty when the action is executed, it is defaulted to \~.

All text fields may contain any of the escape sequences described in Escape Sequences.

Note that where running stepwise the function is only performed once if the source list or destination is a named variable.

The action test state will be set to true if an item was extracted, otherwise false.
