FORTRAN is the father of programming languages in current computer operations, and it is the first language that can convert mathematical formulas into computer programs. After the successful commercialization of IBM in 1957, FORTRAN officially began to assist the development of many engineering application software. FORTRAN is good at mathematical function operation, which is mainly used in numerical analysis, system simulation and automatic control. Program content architecture includes variable definition, function, subroutine, main program, etc. Because of FORTRAN, engineers and scientists can write programs in a more natural language for the first time. It plays an extremely important role in scientific calculation (such as aerospace, geological exploration, weather forecast and construction engineering), so it plays an important role in the field of engineering software design oriented to programming language.

The first Fortran language was developed in 1957, and was later improved into a more structured language called Fortran 77 in 1977. 199 1 adds the concept of object-oriented and provides pointers. At the same time, the function of array has been strengthened, and the form of old Fortran has been greatly improved, which is called Fortran 90. After more than 40 years' development, with the repeated updates of FORTRAN language and the emergence of corresponding development systems, its functions have been continuously improved. The latest version of the development system has almost all the characteristics of VC and VB, such as graphical interface programming and database. At present, FORTRAN is still the first choice for computer programming language courses offered in engineering colleges.

After the introduction of Fortran 90, the traditional Fortran language has a modern flavor. Microsoft integrates Fortran 90 into Developer Strudio IDE, which makes Fortran 90 truly realize visual programming and can * * * enjoy the rich resources of Microsoft window platform.
