State32

Change-state32

Modifying constructor for state32 structures.

Syntax

(change-state32 x 
                [:xregfile <xregfile>] 
                [:pc <pc>] 
                [:mem <mem>] 
                [:error <error>])

This is an often useful alternative to make-state32.

We construct a new state32 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
