Fortran (/ ˈ f ɔːr t r æ n /; formerly FORTRAN) is a third generation, compiled, imperative programming language that is especially suited to numeric computation and scientific computing.
GNU Fortran (GFortran) is an implementation of the Fortran programming language in the GNU Compiler Collection (GCC), an open-source and free software project maintained in the open-source programmer community under the umbrella of the GNU Project. It is the successor to previous compiler versions in the suite, such as g77.
WATFIV (Waterloo FORTRAN IV), developed at the University of Waterloo, Canada is an implementation of the Fortran computer programming language. It is the successor of WATFOR . WATFIV was used from the late 1960s into the mid-1980s.
According to the instruction manual for IFTRAN, a General Research report suggest this rationale for the use of a FORTRAN pre-processor: "While the newer structured languages such as PASCAL are enjoying an unusual popularity, particularly in educational institutions, the workhorse language of scientists and engineers is still FORTRAN. FORTRAN ...
ROSE: an open source compiler framework to generate source-to-source analyzers and translators for C/C++ and Fortran, developed at Lawrence Livermore National Laboratory MILEPOST GCC : interactive plugin-based open-source research compiler that combines the strength of GCC and the flexibility of the common Interactive Compilation Interface that ...
A single program deck, with individual subroutines marked. The markings show the effects of editing, as cards are replaced or reordered. Many early programming languages, including FORTRAN, COBOL and the various IBM assembler languages, used only the first 72 columns of a card – a tradition that traces back to the IBM 711 card reader used on the IBM 704/709/7090/7094 series (especially the ...
Fortran has five intrinsic data types: INTEGER, REAL, COMPLEX, LOGICAL and CHARACTER.Each of those types can be additionally characterized by a kind.Kind, basically, defines internal representation of the type: for the three numeric types, it defines the precision and range, and for the other two, the specifics of storage representation.
For more information on Fortran standards, a number or resources are available, such as the Wikipedia Fortran entry or the Fortran wiki page. The Intel Fortran package included the Intel Array Visualizer, a visualization tool for scientific formats such as FITS and netCDF , which can produce x-y plots, contour plots, and image plots, and save ...
