Examples:
(boole boole-clr 3) => 3
(boole boole-set 7) => 7
;with two arguments always returns
; integer1
I
(boole boole-1 1 B) => 1
(boole boole-2 1 B) => B
As a matter of style the explicit logical functions such as logand, logior,
and logxor are usually preferred over the equivalent forms of boole. boole
is useful, however, when you want to generalize a procedure so that it can
use one of several logical operations.

of Bit-wise Logical Operations" in Symbolics Common Lisp: Language Concepts.
boole-l
Constant
This constant can be used as the fIrst argument to the function boole; it
specilles a bit-wise logical operation that returns the irrst integer argument
of boole.
boole-2
Constant
This constant can be used as the irrst argument to the function boole; it
specilles a bit-wise logical operation that returns the last integer argument
of boole.
boole-and
Constant
This constant can be used as the irrst argument to the function boole; it
specifIes a bit-wise logical and operation to be performed on the integer arguments
of boole.
boole-andcl
Constant
This constant can be used as the fIrst argument to the function boole; it
specilles a logical operation to be performed on the integer arguments of
boole, namely, a bit-wise logical and of the complement of the first integer
argument with the next integer argument.
boole-andc2
Constant
This constant can be used as the fIrst argument to the function boole; it
specifies a logical operation to be performed on the integer arguments of
boole, namely, a bit-wise logical and of the irrst integer argument with the
complement of the next integer argument.
