Ienv

Change-ienv

Modifying constructor for ienv structures.

Syntax

(change-ienv x 
             [:uchar-format <uchar-format>] 
             [:schar-format <schar-format>] 
             [:char-format <char-format>] 
             [:short-format <short-format>] 
             [:int-format <int-format>] 
             [:long-format <long-format>] 
             [:llong-format <llong-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
