The development of a revised standard to succeed FORTRAN 77 would be repeatedly delayed as the standardization process struggled to keep up with rapid changes in computing and programming practice. In the meantime, as the "Standard FORTRAN" for nearly fifteen years, FORTRAN 77 would become the historically most important dialect.
This standard, designated FORTRAN 77, introduced many new statements into the language. In fact, the previous language standard FORTRAN 66 is a very small document and describes, what is in effect, a subset of most implementations of FORTRAN. For example, the WATFIV and WATFOR-11 implementations are based upon the IBM definition of FORTRAN-IV.
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.
F was developed as a modern Fortran, thus making it a subset of Fortran 95. [2] It combines both numerical and data abstraction features from these languages. F is also backwards compatible with Fortran 77, allowing calls to Fortran 77 programs. F was implemented on top of compilers from NAG, Fujitsu, Salford Software and Absoft.
American Standard FORTRAN. American Standards Association, X3.9-1966. p. 38. 4.2.6 Hollerith Type. A Hollerith datum is a string of characters. This string may consist of any characters capable of representation in the processor. The blank character is a valid and significant character in a Hollerith datum.
New Fortran statements, such as FORALL, and the ability to create PURE (side effect free) procedures; Compiler directives for recommended alignment and distribution of array data (influenced by the earlier Fortran D [1] [2] and Vienna Fortran research efforts) Compiler directive for specifying processor arrangements (e.g., rank, extent, etc.)
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 ...
Coarray Fortran (CAF), formerly known as F--, started as an extension of Fortran 95/2003 for parallel processing created by Robert Numrich and John Reid in the 1990s. The Fortran 2008 standard (ISO/IEC 1539-1:2010) now includes coarrays (spelled without hyphen), as decided at the May 2005 meeting of the ISO Fortran Committee; the syntax in the Fortran 2008 standard is slightly different from ...
