Stmt-null

Change-stmt-null

Modifying constructor for stmt-null structures.

Syntax

(change-stmt-null x 
                  )

This is an often useful alternative to make-stmt-null.

We construct a new stmt-null 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))
