Pnumber-number-digit

Change-pnumber-number-digit

Modifying constructor for pnumber-number-digit structures.

Syntax

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

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

We construct a new pnumber-number-digit 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.
