Vl-enum

Change-vl-enum

Modifying constructor for vl-enum structures.

Syntax

(change-vl-enum x 
                [:basetype <basetype>] 
                [:items <items>] 
                [:pdims <pdims>] 
                [:udims <udims>])

This is an often useful alternative to make-vl-enum.

We construct a new vl-enum 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

This is an ordinary change- macro introduced by defprod.
