Expr-postinc

Change-expr-postinc

Modifying constructor for expr-postinc structures.

Syntax

(change-expr-postinc x 
                     [:arg <arg>])

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

We construct a new expr-postinc 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))
