Pnumber-number-dot

Change-pnumber-number-dot

Modifying constructor for pnumber-number-dot structures.

Syntax

(change-pnumber-number-dot x 
                           [:number <number>])

This is an often useful alternative to make-pnumber-number-dot.

We construct a new pnumber-number-dot 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.
