Modinst

Change-modinst

Modifying constructor for modinst structures.

Syntax

(change-modinst x 
                [:instname <instname>] 
                [:modname <modname>])

This is an often useful alternative to make-modinst.

We construct a new modinst 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.
