G-boolean

Change-g-boolean

Modifying constructor for g-boolean structures.

Syntax

(change-g-boolean x 
                  [:bool <bool>])

This is an often useful alternative to make-g-boolean.

We construct a new g-boolean structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

This is an ordinary change- macro introduced by defprod.

                         'change-g-boolean
                         'nil))
