Statement-block

Change-statement-block

Modifying constructor for statement-block structures.

Syntax

(change-statement-block x 
                        [:get <get>])

This is an often useful alternative to make-statement-block.

We construct a new statement-block 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.

                         'change-statement-block
                         'nil))
