Ienv

Change-ienv

Modifying constructor for ienv structures.

Syntax

(change-ienv x 
             [:version <version>] 
             [:char+short+int+long+llong+bool-format <char+short+int+long+llong+bool-format>])

This is an often useful alternative to make-ienv.

We construct a new ienv 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
