Svstmt-if

Change-svstmt-if

Modifying constructor for svstmt-if structures.

Syntax

(change-svstmt-if x 
                  [:cond <cond>] 
                  [:then <then>] 
                  [:else <else>])

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

We construct a new svstmt-if 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 defprod.

                           (:then . svstmt-if->then)
                           (:else . svstmt-if->else))
                         'change-svstmt-if
                         'remake-svstmt-if))
