Schar-format

Change-schar-format

Modifying constructor for schar-format structures.

Syntax

(change-schar-format x 
                     [:signed <signed>] 
                     [:trap <trap>])

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

We construct a new schar-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
