Fortran: Programs
built 658 days ago
Abstract: Fortran M is a small set of extensions to Fortran 77 that supports a modular approach to the design of message-passing programs. It has the following features. (1) Modularity. Programs are constructed by using explicitly-declared communication channels to plug together program modules called processes. A process can encapsulate common data, subprocesses, and internal communication. (2) Safety.

The Fortran language features described are intended to be a fairly comprehensive overview of the Fortran language; full details may be found in any of several Fortran textbooks. Only those features widely used in new programs are described, as few of the historic features are used in modern programs. Still, most have been retained in the language to maintain backward compatibility.

The following is a Fortran for .NET console application that invokes C#, Fortran, and Visual Basic .NET class methods. The Fortran and VB classes inherit a method from the C# base class and override another method. This can be interpreted as: the Fortran main is the dog trainer, and the Fortran and VB dogs inherited the roll-over behavior from the C# dog, but have their own bark behavior - a canine example of object-oriented programming.

Fortran was one of the first widely used high-level programming languages when assembly was one of the only ways to program. There had been high-level programming languages before FORTRAN, but it was the first widely successful one.

It was the development of Fortran II that made it possible to use Fortran for large problems without using excessive compiling time. Fortran II permitted a program to be broken down into subprograms which could be tested and debugged separately. With Fortran II in full operation, the use of Fortran spread very rapidly. Many 704 installations started to use nothing but Fortran. A revolution was taking place in the scientific computing field, but many of the spokesmen for the computer field were unaware of it. A number of major projects that were at crucial points in their development in 1957-1959 might have proceeded quite differently if there was more general awareness of the extent to which the use of Fortran had been accepted in many major 704 installations.

The headline reads John W. Backus, 82, Fortran developer, dies. May he rest in peace. FORTRAN, short for "formula translator", was developed in 1957 and fifty years later, it is still of immeasurable value to researchers at universities all over the world.
