State64

Change-state64

Modifying constructor for state64 structures.

Syntax

(change-state64 x 
                [:xregfile <xregfile>] 
                [:pc <pc>] 
                [:mem <mem>] 
                [:error <error>])

This is an often useful alternative to make-state64.

We construct a new state64 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.
