Fortran 90

(Previously "Fortran 8x" and "Fortran Extended") An extensive enlargement of Fortran 77. Fortran 90 has derived types, assumed shape arrays, array sections, functions returning arrays, case statement, module subprograms and internal subprograms, optional and keyword subprogram arguments, recursion, and dynamic allocation. It is defined in ISO 1539:1991, soon to be adopted by ANSI.

Finally, for the reader unfamiliar with MATLAB, we have included an appendix that describes MATLAB and discusses its similarities with APL and Fortran 90.

Techniques for the Translation of MATLAB Programs into Fortran 90

This is known as Fortran 90 and it is hoped that eventually it will come into general use to replace Fortran 77.

From Fortran and Algol to object-oriented languages

It continues the Fortran tradition of providing a balanced mix of features for writing portable but efficient programs, and is realized by defining a set of standard extensions to Fortran 90. High-level constructs such as FORALL are provided where advanced compilers are believed capable of generating efficient code for different hardware.

FORESYS 2.1 supports the development of quality assurance and migration to Fortran 90 and 95, providing complete analyses of both Fortran products and detecting errors that may be missed by compilers or link editors.
