Major Section:  PROGRAMMING

When integers are viewed in their two's complement representation, logandc1 returns the bitwise logical `and' of the second with the bitwise logical `not' of the first.

The guard for logandc1 requires its arguments to be integers. Logandc1 is defined in Common Lisp. See any Common Lisp documentation for more information.
