Non-structured programming is the historically earliest programming paradigm capable of creating Turing-complete algorithms. It has been followed historically by procedural programming and then object-oriented programming, both of them considered as structured programming.
Unstructured programming has been heavily criticized for producing hardly-readable ("spaghetti") code and is sometimes considered a bad approach for creating major projects, but had been praised for the freedom it offers to programmers and has been compared to how Mozart wrote music.
There are both high- and low-level programming languages that use non-structured programming. These include early versions of BASIC (such as MSX BASIC and GW-BASIC), JOSS, FOCAL, MUMPS, TELCOMP, COBOL, machine-level code, early assembler systems (without procedural metaoperators), assembler debuggers and some scripting languages such as MS-DOS batch file language.
Famous quotes containing the word programming:
“If there is a price to pay for the privilege of spending the early years of child rearing in the driver’s seat, it is our reluctance, our inability, to tolerate being demoted to the backseat. Spurred by our success in programming our children during the preschool years, we may find it difficult to forgo in later states the level of control that once afforded us so much satisfaction.”
—Melinda M. Marshall (20th century)
