Stmt-ifelse

Change-stmt-ifelse

Modifying constructor for stmt-ifelse structures.

Syntax

(change-stmt-ifelse x 
                    [:test <test>] 
                    [:then <then>] 
                    [:else <else>])

This is an often useful alternative to make-stmt-ifelse.

We construct a new stmt-ifelse 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
