Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making specific disciplined use of the structured control flow constructs of selection (if/then/else) and repetition (while and for), block structures, and subroutines.
Considered harmful was popularized among computer scientists by Edsger Dijkstra's letter "Go To Statement Considered Harmful", [3] [4] published in the March 1968 Communications of the ACM (CACM), in which he criticized the excessive use of the GOTO statement in programming languages of the day and advocated structured programming instead.

Corrado Böhm (17 January 1923 – 23 October 2017) was an Italian computer scientist and Professor Emeritus at the University of Rome "La Sapienza", known especially for his contributions to the theory of structured programming, constructive mathematics, combinatory logic, lambda calculus, and the semantics and implementation of functional programming languages.
A key concept of structured programming is the local variable, which holds its value separate from other variables with the same name in other locations in the composite program. As BASIC did not have the concept of scope, many programs relied on the global behaviour and used variables to pass information in and out of subroutines.
Knuth discusses software patenting, structured programming, collaboration and his development of TeX. The oral history discusses the writing of The Art of Computer Programming.

JSP is not used to structure programs at the level of classes and objects, although it can helpfully structure control flow within a class's methods. JSP uses a diagramming notation to describe the structure of inputs, outputs and programs, with diagram elements for each of the fundamental component types. A simple operation is drawn as a box.
In the early 1980s, the company had multiple offices in North America and Europe and a staff of 150 people. They trained over 250,000 people in the topics of structured programming, structured design, structured analysis, logical data modeling and project management. [1] In 1986, Yourdon sold the consulting company.
Sequence is the simplest structure to show on a Warnier/Orr diagram. Within one level of hierarchy, the features listed are shown in the order in which they occur. In other words, the step listed first is the first that will be executed (if the diagram reflects a process), while the step listed last is the last that will be executed.
