This operator may only be used in the following ways:
- The expression `` record. symbol'' yields the
attribute value of the attribute of record whose name is
symbol. If there is no attribute in record whose name is
symbol, the expression yields the special symbol nil.
- The expression `` list. number'' yields the element of
list at position number. If there is no element at position
number in list, the expression yields the special symbol
nil.
- The expression `` value. list'', where list
is a list < e1, e2,
> of symbols and/or numbers, serves
as an abbreviation for `` value. e1. e2
''.
