Svstmt-while

Change-svstmt-while

Modifying constructor for svstmt-while structures.

Syntax

(change-svstmt-while x 
                     [:cond <cond>] 
                     [:body <body>] 
                     [:next <next>])

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

We construct a new svstmt-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
