Hex-digit

Change-hex-digit

Modifying constructor for hex-digit structures.

Syntax

(change-hex-digit x 
                  [:get <get>])

This is an often useful alternative to make-hex-digit.

We construct a new hex-digit 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

                         'nil))
