What is the .M3 File Extension?

.M3 File Extension Description:

The .m3 file extension is defined as the language source code file, generated by the Modula-3 Programming language. Modula-3 is categorized as a system programming language, which was derived from Mesa and is similar to the function of Object Pascal, Euclid and Oberon. The objective in generating .m3 file extensions is to create safe and simple applications that can cater to the requirements of system developers. Generally, the operation of Modula-3 in generating files with the file extension .m3 is aimed at two main purposes: the creation of a systematic and simple system and to generate better robustness.

The Modula-3 application builds on one of the better features of its predecessor, which is the building of specific module interfaces. The .m3 file extension contains objects, classes, garbage collection, threads and exception handling, which are generated by the programming environment. Source code files using the file extension .m3 usually find implementation in teaching, research and industrial projects, because it promotes ideal programming practices accompanied by outstanding programming libraries that can generate graphical user interfaces.

The file extension .m3 is controlled in at least three central web servers that cater explicitly to Modula-3 associated data and source codes, which are the, Ecole Polytechnique de Montre and DEC SRC. The file extension .m3 is also supported by User Networks (Usenet) newsgroups that discuss various issues related to programming, debugging, and other Modula-3 concerns. Despite building on the features of Modula-2, the .m3 file extensions generated by Modula-3 are not suitable Modula-2 applications and vice versa. A tool is available that will allow .m3 file extensions to be supported by both versions of the programming language.

Programmers who wish to contribute their source codes in .m3 file extension format are very much welcome, because they contribute to the growth of the language, including expanding the knowledge of every Modula programmer. The file extension .m3 provides support to at least 25 different platforms with the implementation of the Modula-3 compiler. The .m3 file extension has been instrumental in the development of real world applications including the SPIN OS, which was a project of the University of Washington. The source code of the kernel for the OS was written in Modula-3 with the .m3 file extension.
