Plexeme-number

Change-plexeme-number

Modifying constructor for plexeme-number structures.

Syntax

(change-plexeme-number x 
                       [:number <number>])

This is an often useful alternative to make-plexeme-number.

We construct a new plexeme-number 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
