Statement-if

Make-statement-if

Basic constructor macro for statement-if structures.

Syntax

(make-statement-if [:test <test>] 
                   [:body <body>])

This is the usual way to construct statement-if structures. It simply conses together a structure with the specified fields.

This macro generates a new statement-if structure from scratch. See also change-statement-if, which can "change" an existing structure, instead.

Definition

                       'make-statement-if
                       nil))

                    :exec test))
         (body (mbe :logic (block-fix body)
                    :exec body)))
      (cons :if (list test body)))))
