Jackson's aim was to make COBOL batch file processing programs easier to modify and maintain, but the method can be used to design programs for any programming language that has structured control constructs— sequence, iteration, and selection ("if/then/else").
The later steps of JSD produce the code of the final system. Jackson’s first method, Jackson Structured Programming (JSP), is used to produce the final code. The output of the earlier steps of JSD are a set of program design problems, the design of which is the subject matter of JSP.
Jackson Structured Programming (JSP) was the first software development method that Jackson developed. It is a program design method, and was described in his book Principles of Program Design. [8] JSP covers the design of individual programs, but not systems.
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. The project was a great engineering success, and managers at other companies cited it in support of ...
Is Perl and c modern programming languages? I wouldn't say so. C# and Java are modern, Perl and C are not. -- (Anon user) Well, C is a 1970s implementation of the structured programming concepts of the 1960s that became popular during the 1980s, so calling it modern could be stretching things a bit in the 2000s ...
SSADM is one particular implementation and builds on the work of different schools of structured analysis and development methods, such as Peter Checkland's soft systems methodology, Larry Constantine's structured design, Edward Yourdon's Yourdon Structured Method, Michael A. Jackson's Jackson Structured Programming, and Tom DeMarco's ...
Jackson Structured Programming (JSP) is a method for structured programming based on correspondences between data stream structure and program structure. LePUS3 is an object-oriented visual Design Description Language and a formal specification language that is suitable primarily for modeling large object-oriented ( Java , C++ , C# ) programs ...
In computer programming, a block or code block or block of code is a lexical structure of source code which is grouped together. Blocks consist of one or more declarations and statements. A programming language that permits the creation of blocks, including blocks nested within other blocks, is called a block-structured programming language.
