Symbol-terminal

Change-symbol-terminal

Modifying constructor for symbol-terminal structures.

Syntax

(change-symbol-terminal x 
                        [:get <get>])

This is an often useful alternative to make-symbol-terminal.

We construct a new symbol-terminal 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

                         'nil))
