Formal specification is a technique for accurately modelling computer-based structures that mixes strategies from software program engineering and mathematical common sense. during this booklet the authors describe algebraic and state-based specification strategies from the unified view of the typical Object-oriented Language for layout, chilly, a wide-spectrum language within the culture of VDM and Z. The kernel language is defined intimately, with many examples, together with: set illustration, a demonstrate machine, an INGRES-like database process, and a line editor. basic concepts reminiscent of preliminary algebra semantics, free semantics, partial capabilities, hiding, sharing, predicate and dynamic common sense, abstraction capabilities, illustration of invariants and black-box correctness also are offered. extra complex rules, for instance Horn common sense, and big platforms are given within the ultimate half. Appendices comprise complete information of the language's syntax and a specification library. innovations for software program improvement and layout are emphasized all through, so the publication should be a great selection for classes in those parts.

Sample text

Specification: Program Lister Function This program shall process the lines of source code in an Ada program, producing a listing of the program, with line numbers preceding each executable line of source code, followed by a report of the counts of executable and comment source lines of code. Definitions Line of source code: A line of an Ada program file (all characters up to the line terminator), which may contain statements or parts of statements, comments, and/or blanks. Blank line: A line of source code that does not contain any nonblank characters.

The main module of the design becomes the main program, and subsections develop into procedures or functions. As an example, let's start the functional design for making a cake.  Figure 1­5 illustrates the hierarchy of such a functional decomposition.  This form of information hiding is based on procedural or functional abstraction.  We believe that the solutions to large­scale problems are better designed with another method: object­oriented design.  These entities, called objects, collaborate and interact to solve the problem.

One person concentrates on spreading the bread with peanut butter and jelly; someone else is responsible for growing the peanuts. Package A group of logically related entities that may include types and subtypes, constants of those types and subtypes, and subprograms with parameters of those types and subtypes.  Your first Ada program probably included the statement with Text_IO; to declare your intent to use resources provided by the package Text_IO.  The package body provides the implementation of the resources defined in the package specification; the insides of the watch.
