Stmt-while

Change-stmt-while

Modifying constructor for stmt-while structures.

Syntax

(change-stmt-while x 
                   [:test <test>] 
                   [:body <body>])

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

We construct a new stmt-while 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
