Integer-format

Change-integer-format

Modifying constructor for integer-format structures.

Syntax

(change-integer-format x 
                       [:pair <pair>])

This is an often useful alternative to make-integer-format.

We construct a new integer-format 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-integer-format
                         'nil))
