Major-frame

Change-major-frame

Modifying constructor for major-frame structures.

Syntax

(change-major-frame x 
                    [:bindings <bindings>] 
                    [:rule <rule>] 
                    [:phase <phase>] 
                    [:minor-stack <minor-stack>])

This is an often useful alternative to make-major-frame.

We construct a new major-frame 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.
