Tree-list-tuple9

Change-tree-list-tuple9

Modifying constructor for tree-list-tuple9 structures.

Syntax

(change-tree-list-tuple9 x 
                         [:1st <1st>] 
                         [:2nd <2nd>] 
                         [:3rd <3rd>] 
                         [:4th <4th>] 
                         [:5th <5th>] 
                         [:6th <6th>] 
                         [:7th <7th>] 
                         [:8th <8th>] 
                         [:9th <9th>])

This is an often useful alternative to make-tree-list-tuple9.

We construct a new tree-list-tuple9 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

This is an ordinary change- macro introduced by fty::defprod.
