List.at(N)
This returns the Nth value of the List as a string. List can be either Set or List type attributes (or string literal, regex pattern, or expression equivalents thereof).
The operator is zero-based, i.e. an N value of 0 returns the first list item, an N of 1 returns value #2, etc. If the value of N exceeds the number of items in the list an empty string (blank value) is returned. A negative number returns an item numbering in reverse - but one-based not zero-based - so '-1' returns the last item on the list, '-2' the last but one item, etc..
Examples (where $MyList is "ant;bee;cow"):
$MyString = $MyList.at(0) returns "ant"
$MyString = "XX;YY;ZZ".at(2) returns "ZZ"
$MyString = $MyList.at(5) returns "" (nothing)
$MyString = $MyList.at(-2) returns "bee"
