Modula-3 is a programming language conceived as a successor to an upgraded version of Modula-2 known as Modula-2+. It has been influential in research circles (influencing the designs of languages such as Java , C# , Python [ 8 ] and Nim ), but it has not been adopted widely in industry.
The SPIN operating system is a research project implemented in the computer programming language Modula-3, and is an open source project. It is designed with three goals: flexibility, safety, and performance. SPIN was developed at the University of Washington.
Another early modular language was Mesa (1970s), by Xerox PARC, and Wirth drew on Mesa as well as the original Modula in its successor, Modula-2 (1978), which influenced later languages, particularly through its successor, Modula-3 (1980s). Modula's use of dot-qualified names, like M.a to refer to object a from module M, coincides with notation ...
Baby Modula-3 is a functional programming sublanguage of Modula-3 (safe subset) programming language based on ideals invented by Martín Abadi.It is an object-oriented programming language for studying programming language design; one part of it is implicitly prototype-oriented, and the other is explicitly statically typed designed for studying computer science type theory.
The Modula programming language is a descendant of the Pascal language. It was developed in Switzerland , at ETH Zurich , in the mid-1970s by Niklaus Wirth , the same person who designed Pascal. The main innovation of Modula over Pascal is a module system , used for grouping sets of related declarations into program units; hence the name Modula .
In some languages, notably those influenced by Modula-3 (including Python and Go), modules are objects, and scope resolution within modules is a special case of usual object member access, so the usual method operator . is used for scope resolution.
For example, the expression "5 mod 2" evaluates to 1, because 5 divided by 2 has a quotient of 2 and a remainder of 1, while "9 mod 3" would evaluate to 0, because 9 divided by 3 has a quotient of 3 and a remainder of 0. Although typically performed with a and n both being integers, many computing systems now allow other types of numeric operands.
Oberon is a general-purpose programming language first published in 1987 by Niklaus Wirth and the latest member of the Wirthian family of ALGOL-like languages (Euler, ALGOL W, Pascal, Modula, and Modula-2).
