  Structured programming - Wikipedia, the free encyclopedia
It is possible to do structured programming in almost any procedural programming language, but since about 1970 when structured programming began to gain popularity as a technique, most new procedural programming languages have included features to encourage structured programming (and sometimes have left out features that would make unstructured programming easy).
Structured programming theorists gained a major ally in the 1970s after IBM researcher Harlan Mills applied his interpretation of structured programming theory to the development of an indexing system for the New York Times research file.
Some programs, particularly parsers and communications protocols, have a number of states that follow each other in a way that is not easily reduced to the basic structures.

 Felgall Software - Structured Programming
Structured programming is one of the several different ways in which a programming language can be constructed.
A structured program may be written out using pseudo code prior to being translated into whatever programming language that the program is to be written in.
Structured programming provides a number of constructs that are used to define the sequence in which the program statements are to be executed.

 E.W. Dijkstra Archive: Structured programming (EWD268)
By "intrinsically large" I mean programs that are large due to the complexity of their task, in contrast to programs that have exploded (by inadequacy of the equipment, unhappy decisions, poor understanding of the problem, etc.).
A program therefore should be conceived and understood as a member of a family; it should be so structured out of components that various members of this family, sharing components, do not only share the correctness demonstration of the shared components but also of the shared substructure.
Such a joint refinement of data structure and associated statements should be an isolated unit of the program text: it embodies the immediate consequences of an (independent) design decision and is as such the natural unit of interchange for program modification.

Structured programming is a modular form of programming.
In structured programming, the called module performs one function, and you must accept the function as it is written, or you can copy code and modify it to meet your needs.
In structured programming, all data is passive; a record of data is passed from one subroutine to another.

 Computer programming - Wikibooks, collection of open-content textbooks
Programming a computer can be performed in one of numerous languages, ranging from a higher-level language to writing directly in low-level machine code (that is, code that more directly controls the specifics of the computer's hardware).
C is a system programming language and has a fairly simple syntax and a small set of keywords but with an extensive set of rules attached to those.
Initially, Pascal was a hypothetical language intended to teach students structured programming, and generations of students have "cut their teeth" on Pascal as an introductory language in undergraduate courses.

 SIGPLAN Notices
With the advent of structured programming and GOTO-less programming, a method is needed to model computation in simply ordered structures, each representing a complete thought possibly defined in terms of other thoughts as yet undefined.
During one of these phases a flowchart may be drawn to describe the program at a level of abstraction somewhere between the problem statement and the code of the completed program.
Certain control structures in programming languages, such as iteration, have no direct translation to flowchart language and must be built from simpler control structures, thereby losing the forest in the trees.

 Define structured programming - a Whatis.com definition - see also: modular programming   (Site not responding. Last check: 2007-10-07)
Structured programming frequently employs a top-down design model, in which developers map out the overall program structure into separate subsections.
In this model (which is often considered to be synonymous with structured programming, although other models exist) the developer separates programs into subsections that each have only one point of access and one point of exit.
Object-oriented programming (OOP) can be thought of as a type of structured programming, uses structured programming techniques for program flow, and adds more structure for data to the model.

The awarding of a contract in February 1974 to IBM to define structured programming was an outgrowth of that briefing.
Structured Programming itself, the restriction during design and implementation to the three programming constructs of sequence, alternation, and iteration, was considered only one component of structured programming.
No textbook presentation of Harlan Mills' ideas on structured programming was available until 1979 (Linger 79), and even that book does not discuss the broader issues of the environment in which structured programming operates, and the issues involved with managing teams who are applying structured programming techniques, that are considered in the RADC study.

 Structured Programming
In early programming languages, like Fortran (first invented in 1954) and various low level machine languages, the goto statement allowed the computer to deviate from the sequential execution of the program instructions.
This was the birth of the discipline of Structured Programming.
Structured programming is a program written with only the structured programming constructions: (1) sequence, (2) repetition, and (3) selection.

 SIGCHI Bulletin Vol.29 No.4, October 1997: Structured Programmers Learning Object-Oriented Programming   (Site not responding. Last check: 2007-10-07)
One commonly expressed problem with this training task is that the interaction between programmers and their programming language environment appears to be significantly altered during both design and coding phases when using an OOP language versus earlier, so-called structured, approaches.
In structured programming, while analysis starts with a consideration of real-world problems, the real-world focus is lost as requirements are transformed into a series of data flow diagrams.
In a structured program, data (e.g., employees, orders, or sales records) are essentially passed to functions (e.g., print, display, add, change, and delete routines) that act on the data as required.

Event-driven programming vastly improves on older models because it transfers the flow of the program from the programmer to the user.
The meat of event-driven programming is in the event-handlers.
If your program is event-driven, you can't assume a certain number of integers, you can't even assume that any integers have been entered at all.

 STRUCTURED PROGRAMMING: April, 1993 -- #51
Bjarne and his gang are having loads of fun piling every conceivable expression of program logic and abstraction into C++, making it easily the largest, most complex, and least-understood programming language in history.
I'd like to think that, away from the excesses of C++, most workaday programming languages are converging to what ANSI C, Microsoft Basic, and Turbo Pascal all are: Structured programming languages with simple but robust designs.
Programming as we know it is indeed the most intoxicating kind of fun (or maybe the second most) but if something better comes along, we're doing no one any favors by clinging to the old ways.

 The Pascal Programming Language
His principle objectives for Pascal were for the language to be efficent to implement and run, allow for the development of well structured and well organized programs, and to serve as a vehicle for the teaching of the important concepts of computer programming.
Pascal also draws programming components from ALGOL 68 and ALGOL-W. The original published definition for the Pascal language appeared in 1971 with latter revisons published in 1973.
It was designed to teach programming techiques and topics to college students and was the language of choice to do so from the late 1960's to the late 1980's.
