Jstatem-expr

Change-jstatem-expr

Modifying constructor for jstatem-expr structures.

Syntax

(change-jstatem-expr x 
                     [:get <get>])

This is an often useful alternative to make-jstatem-expr.

We construct a new jstatem-expr 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))
