Int-value

Change-int-value

Modifying constructor for int-value structures.

Syntax

(change-int-value x 
                  [:int <int>])

This is an often useful alternative to make-int-value.

We construct a new int-value 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 fty::defprod.

                         'change-int-value
                         'nil))
