<A NAME=7700>Ordinarily</A> the result of calling a Lisp function is a single Lisp object.
|
||
|
|
Sometimes, however, it is convenient for a function to compute several
|
||
|
|
objects and return them.
|
||
|
|
Common Lisp provides a mechanism for handling multiple values directly.
|
||
|
|
This mechanism is cleaner and more efficient than the usual tricks
|
||
|
|
involving returning a list of results or stashing results in global
|
||
|
|
variables.
