What is the .F77 File Extension?

.F77 File Extension Description:

Files using the F77 file extension are source codes used by the Fortran 77 standard. FORTRAN is a general purpose programming language created mainly for use in mathematical computations. FORTRAN is the first high level programming language released, gradually adding features for its user's benefit, which consisted mainly of scientist and engineers. To be able to maintain compatibility with older programs, development of the programming language consisted of several additions of new features without removing old ones. This is aptly called software inertia.

By convention, FORTRAN versions are denoted by the last two digits of the year that the standard was released. Fortran 77 therefore signifies that this standard was released in the year 1977. It was produced by a committee of the American National Standards Institute (ANSI) and was later on adapted by the International Standards Organization (ISO). Its definition was then published as ANSI X3.9-1978 and ISO 1539-1980. ANSI Standard has defined two different levels of Fortran 77. Subset FORTRAN was designed to be used on computers that are not powerful enough to handle full language. The second level is the full Fortran 77 language. Programs utilizing the ANSI FORTRAN 77 and not using anything outside the standard will surely run on any computer, which has a Fortran 77 compiler making Fortran programs portable to many different machine platforms.

To date, Fortran 77 is the most commonly used version of FORTRAN. Most current FORTRAN systems are created and designed to conform to the Fortran 77 standard. Source codes files with the F77 file extension have good characteristics in handling character strings and numbers. The files with the F77 file extension also have powerful file handling and input and output facilitates, which makes it appropriate for a wide range of applications than ever before.

FORTRAN's popularity is due to its combination of different properties. Creating files using the F77 file extension and using the Fortran 77 standard are simple enough, that not only scientist and engineers exclusively use it. These files with the F77 file extension have an independent compilation of program units, thus allowing the codes to be used on very large applications. A compiled source code with the F77 file extension is a bit high, because the language itself is straightforward to compile, and the techniques for handling are already advanced. These combined properties make it very easy to create new programs derived from old ones.

Do you have errors with .F77 files?

The Usual Reason for .F77 files Errors:

A common and likely cause for .F77 files errors is failure in the Windows program registry - repairs are necessary to protect against further corruption in other applications and/or hardware devices. As long as the errors persist your computer stays capable of possible blue screen errors, hardware failure and fatal crashes.

What are the Symptoms of .F77 files Errors?

Common symptoms from .F77 files errors include poor pc performance, extended software load times, problems loading files, excessive suspensions in software procedures, software closing without showing an indication of error, input freezing and software lock up.
