Query: Exellent book for beginners, esp. without progr. background

A person who just starts his programming experience and it happenes to be ABAP/4 may find a well-organized way how to code some programming task. However, after initial exposure to ABAP/4 the person should run away from this book in order to get in-depth understanding of coding complex applications. The strong side of the book: consistency in conveying the material to novice programmers; the weak point: there's not a clear statement whom it's addressed for.
