S generates the members of S . 4.3 Tables Tables are sets of pairs each of which consists of a key and a corresponding value. The key and its corresponding value may be of any type, and the value for any key can be looked up automatically. Thus, tables provide a form of associative access in contrast with the positional access to values in lists. The default value is used for keys that are not assigned another value.
Tables grow automatically as new keys are added.
There are augmented assignment operations for all binary operators. The form of the list depends on the value of i . For example, if i is 3, the list contains alternate keys and their corresponding values in T . Text can be written to windows in a variety of type faces and sizes, including proportional-width faces. Characters from the keyboards can be processed as they are typed.
