Svstate

Change-svstate

Modifying constructor for svstate structures.

Syntax

(change-svstate x 
                [:blkst <blkst>] 
                [:nonblkst <nonblkst>])

This is an often useful alternative to make-svstate.

We construct a new svstate 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.
