.M File Extension

Objective-C is most commonly used to implement applications for Apple's Mac OS X and iOS operating systems. Apple's Cocoa API provides the Objective-C programming interface for Mac OS X, and the iOS API provides the programming interface for the iOS platform.

You can open an M file with The MathWorks MATLAB (multiplatform). To open an M file, select Open from the "HOME" or "EDITOR" tabs, choose the M file, then select Open.

Opening an M file with a text or source code editor

Since M files store plain text, you can open them with a text editor, such as Microsoft Notepad (Windows) or Apple TextEdit (Mac), or a source code editor. However, most users open and edit M files with MATLAB since the app provides helpful editing tools not available with third-party apps.

Mercury was written in order to provide a robust language for large real world applications. It includes several error-checking features not provided by other logic programming languages. For example, the language incorporates static analysis that can catch type checking errors before runtime. This enables greater assurance over the correctness of the program and also allows the compiler to generate more efficient code. However, the developer must specify each of the "type," "mode," and "determinism" constructs while programming, which is not necessarily required by other languages.

NOTE: The developmental version of the Mercury compiler is currently distributed in a source code format and does not include compiler binaries. However, a Windows port of Mercury, called winmercury, includes binaries. It also includes Vim syntax highlighting files for source code editing.

Files named "init.m" are initialization files that contain settings that are loaded when the Mathematica program is opened.

NOTE: In order to play M files with FMPMD2000, you need to download the WinFMP.dll and PMDWin.dll files, which are available from the same location.
