A variable may name a location where a value can be stored. A variable that does so is said to be bound to the location. The set of all such bindings in effect at some point in a program is known as the environment in effect at that point. The value stored in the location to which a variable is bound is called the variable's value. By abuse of terminology, the variable is sometimes said to name the value or to be bound to the value.
