Lhatom-var

Change-lhatom-var

Modifying constructor for lhatom-var structures.

Syntax

(change-lhatom-var x 
                   [:name <name>] 
                   [:rsh <rsh>])

This is an often useful alternative to make-lhatom-var.

We construct a new lhatom-var 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
