Glcp-obj-ctrex-p

Change-glcp-obj-ctrex

A copying macro that lets you create new glcp-obj-ctrex-p structures, based on existing structures.

Syntax:

(change-glcp-obj-ctrex x 
                       [:descrip <descrip>] 
                       [:genv <genv>] 
                       [:obj-alist <obj-alist>] 
                       [:dont-care-spec <dont-care-spec>])

This is a sometimes useful alternative to make-glcp-obj-ctrex. It constructs a new glcp-obj-ctrex-p 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.
