"Rationale for the Design of the
Ada® Programming Language"
[Ada '83 Rationale, HTML Version]
CHAPTER 1: Introduction and Preface
This document is divided into chapters covering different aspects of
the language. Most chapters correspond to chapters of the Reference
Manual. Expressions and statements are here regrouped in a single
chapter, since the subject is fairly classical. Conversely, in view of
the importance of the subjects, special chapters are devoted to
numeric types, access types, and derived types, in addition to the
chapter on types. The chapters of the Rationale are fairly independent
(at the cost of some repetition) and can be read in any order.
Most chapters of the Rationale have a common structure. They start
with an introduction to the topic discussed. An informal description
of the language features follows. This description is made in terms of
examples chosen to reflect the major classes of uses of the features
considered.
We believe that the reader will get the spirit of the language reading
these examples. They should help the development of an intuition for
programming style in the Ada language.
A discussion of the technical issues follows, or in some cases is
interspersed with the informal description. Such discussions cover the
major design decisions,hpot their justification, and the interactions with
other aspects of the language.
